BarChart(), Histogram(), Plot() for facet plots: Axis tick lengths are now smaller, to match the lengths for non-facet Plot() visualizations.
Plot(): Parameter lwd renamed line_width. Parameter ts_PIlevel renamed ts_PI.
PieChart(): Parameter lwd renamed line_width. Parameter lty renamed line_type.
Plot(): To jitter either axis coordinate, set to a specific value of jitter_x and/or jitter_y or have the value set by Plot(), indicated by setting the corresponding jitter parameter to NULL. Applying jitter to both the x-axis and y-axis was by design occurring by default for all analyses, probably too aggressive. Now, the default values for a scatterplot of continuous variables is 0. For discrete variables or a VBS plot (violin-box-scatter plot), different formulas provide default jitter values greater than 0, easily overridden by providing specific values.
Plot(): For non-linear values of parameter fit, now provide the MSE of the model fit to the original, non-linear data. Can compare this MSE to that of the linear model by running another analysis, setting fit to "lm".
Plot(): New parameter fit_new to provide values of the x-variable from which to compute (predict) values of the y-variable for linear and non-linear forms specified by the fit parameter, except for "loess".
Plot(): As with origin_y from the previous lessR version, the default value of origin_x favors 0 if there is not too much resulting blank space in the corresponding visualization. Or, manually specify the desired parameter value.
Plot(): For Trellis (facet) plots, axis values in the even hundred thousands are now expressed in K notation, such as 100K instead of 100000, a feature previously added to non-facet plots.
Regression(): The criteria for plotting points as bubbles for a single predictor model was deemed too encompassing. The new criteria are to plot as bubbles by default only when the single predictive variable and the target variable have less than or equal to 12 unique values. Boolean parameter bubble_plot added to override default for displaying the scatterplot of the one predictor variable with the target variable as a bubble plot.
Regression(): Parameter size added to override default for the size of plotted points.
Histogram(): Axis labels were written too far from the corresponding tick marks.
Plot(): A one-variable categorical variable coded as a factor can now be plotted as a bubble plot. If the categorical variable is numerical, add a value of the radius parameter to force as a bubble plot instead of a VBS plot.
style(): Transparency now properly recognized with add_fill colors with specified transparency from add_trans parameter.
style(): Default fill for a superimposed rectangle on a visualization with style(add="rect") changed to light gray with light transparency to allow content within the rectangle to be viewed, "#D9D9D920".
Plot(): New parameter ts_method to specify the estimation method for generating a forecast. The default is "es" for exponential smoothing, the only available previous method. Can now also implement "lm" for least squares linear regression model with seasonality, which de-seasonalizes the data and then adds seasonality back to the estimated regression line.Plot(): To generalize parameter names for multiple estimation methods, all parameters that began with time_ and es_ now begin with ts_. For example, time_unit is now ts_unit, and es_seasons becomes ts_seasons.
Plot(): New parameter value days7 for ts_unit. All other time units are based on the 365 or 366 day year, the interval over which seasons are assessed. Seasonality for days is not generally meaningful assessed over the entire year but can be for days of the week. The time unit of days7 assesses seasonality of days over the 7-day week, such as, for example, more sales on Monday than on Sunday.
Plot(): New parameter origin_y to set the minimum value of the y axis, though the data will not be truncated if the value is larger than the smallest y value, instead triggering an error. This parameter compliments existing parameters origin_x, and also scale_y, which sets the minimum, maximum, and interval for scaling the y axis. Its value is set to 0 by default in relevant situations.
Plot(): New parameter ts_NA to specify treatment of missing values for the y-variable. By default, y missing values, those with value NA, do not plot, leaving a blank space. Or, specify a value such as 0 to replace the NA to plot that y-value for the corresponding date on the x-axis.
STL(): Output data structure provided that consists of four variables: date according to the named date variable and the extracted trend, season, and error components. Example: s <- STL(Qtr, Sales) outputs to the data frame s.
pivot(): When computing a cross-tab table, if the first variable was a factor the analysis would crash. Now fixed.
Plot(): When plotting a time series, x-axis tic lengths and the margin for value labels is refined.
Plot(): Refined the extraction of the date variable and the y variable from a time series used in internal processing, such as identifying leap years to provide more generally accurate dates.
Plot(): When plotting a time series with multiple y values, the y-axis label now properly displays.
Plot(): When plotting a stacked time series, the vertical legend now displays with the proper colors and in the same order as the display of the stacked variables.
Plot(): If plotting daily data with a time unit of "weeks", then dates are plotted as individual dates by days instead of months.
Plot(): If plotting a y categorical variable and an x continuous variable, the number of decimal digits for the displayed statistics is now based on the decimal digits inherent in the continuous variable instead of set at 1.
Plot(): For a time series exponential smoothing forecast, now display SSE and MSE fit indices, the linear trend and seasonal coefficients, and the obtained smoothing parameter values.
Plot(): Improved conversion of character string numeric dates to R type Date.
Plot(): Read dates entered as character strings formatted as:
Plot(): Forecasting output now written to an output list object such as p <- Plot(...) with names out_frcst, out_fitted, out_coefs, and out_params. This output is accessible for showing just part of the output, such as p$out_frcst when writing R Markdown documents from the results.
STL(): Set parameter show_range to TRUE to show the range of each component. Before TRUE was the default.
STL(): Parameter quiet added to suppress text output and parameter do_plot added to suppress the visualization.

Plot(): Turn off the plot with do_plot=FALSE, leaving only text output, now works.
Plot(): If plotting a run chart with multiple y variables, adjacent points are now connected with line segments for each of the y variables. Example: Plot(.Index, c(y1,y2,y3)).
Plot(): Exponential smoothing forecasting implemented with accompanying visualization. New parameters include time_ahead for the number of time_units to forecast into the future, and time_format to provide a specific format for the date variable if not detected correctly by default. Control aspects of the exponential smoothing estimation and prediction algorithms with parameters es_level (alpha), es_trend (beta), es_seasons (gamma), es_type for additive or multiplicative seasonality, and es_PIlevel for the level of the prediction intervals.
Plot(): Character string versions of a date as in a variety of forms as digits, such as "08/18/2024", are now by default converted to variable type of Date. However, this conversion is inherently ambiguous, so the time_format parameter is provided as a means to provide the precise format if needed, including other formats such as "August 18, 2024". Also, a sequence of four-digit integers within the usual range of dates will also convert automatically to a variable of type `Dates.
STL(): A wrapper for Base R stl() that provides additional information and utility:
Date as the x-variable and the time series values as the y-variable instead of an R time series.Date.BarChart(), Histogram(), Plot(): If the x- or y- axis values in the resulting plots all end in 000, then the 000 is replaced with a K, such as 120000 plotted as an axis value of 120K.
LineChart(): Deprecated for years, now removed as its functionality has been incorporated into Plot() and extended with the x-variable of type Date.
Plot(): Parameter run dropped. Instead, to maintain the position of the variable of interest to be plotted, as the y-variable, indicate a run chart by specifying .Index as the x-variable, that is, the first variable listed. That name, beginning with a period, ., indicates data values for the variable Will be created automatically.
Plot(): Increase the default size of the dot in the Cleveland dot plot and related.
Plot(): When parameter time_unit is explicitly set, proper dates are now displayed on the x-axis when there is a by variable.
Plot(): Suggestions are working. To turn off: style(suggest=FALSE).
BarChart(), Histogram(), Plot(): Parameter names by1 and, where applicable, by2, deprecated, replaced with more descriptive new names facet1 and facet2.
Plot(): Using functions from the xts package, when plotting a time series dates are now formatted according to their natural unit. For example, when plotting by years, just years are listed without the month and the day.
Plot(): When plotting a times series and requesting a level of time aggregation with the time_unit parameter that is more detailed than the available data, the analysis appropriately terminates with an error message. For example, if the time series data is monthly and an aggregation of weeks is requested, no analysis is done.
Plot(): For plotting time series data, new parameter n_date_ticks added to override the default number of ticks on the x axis, the date axis.
Plot(): For Trellis (facet or lattice) plots of bar charts and histograms, each panel is labeled with the proper size of text in the corresponding panel strip.vignettes: These extensive examples are moved to the web to save space as the installed lessR was exceeding the accepted maximum limit. The web address is given from library(lessR).

all visualizations: Grid lines not affected in some plots that would add some unintended transparency to the visualizations.
PieChart(): User now warned that the values family of parameters is changed to labels, though the old reference still will work.
Read(): If quiet=TRUE, automatically modified variable names to legal R names are not reported.
all visualizations: Default colors softened a bit with default transparency level moved from 0 to 0.10.
ANOVA(), BarChart(), Histogram(), PieChart(), pivot(), Plot(), Regression(), ttest(): Parameter rows, for subsetting data, deprecated, now named filter to be more consistent with other systems, although rows parameter removed entirely for ANOVA(), pivot(), Regression(), and ttest()to avoid needing therowsparameter as part of the function definition in addition tofilter`.
BarChart(), Histogram(), PieChart(), Plot(): Parameter filter (formerly rows), now reports the number of rows of data before and after the filtering along with the logical statement that defines the filter.

Plot(): If a time series is plotted from a x-axis variable that is not of type Date, then, setting segments=TRUE connects the points (which can vanish if size=0), but the line width parameter lwd was previously not responsive in this context.
Logit(), Regression(): For categorical predictor variables, the conversion to indicator variables now happens before the analysis. All analyses are now only of numeric variables so that the correlation matrix, scatterplot matrix, tolerance, and best subset analyses are now conducted for categorical predictor variables.
Logit(), Regression(): Redundant predictor variables that lead to a singularity is now detected and noted instead of the function crashing.
Logit(): For sigmoid function plot for a single predictor model, right-hand margin adjusted to better display labels of the target variable of varying lengths.

ANOVA(), BarChart(), Histogram(), Plot(), Regression(), ttest(): A tibble that is not in the user workspace, instead in a package, is now properly converted to a standard R data frame upon which the internal function's code depends, which also permits more flexibility in the packaging of data in general to these functions, such as with the pipe operator.
ANOVA(): Overall p-value now available for the one-way ANOVA as the statistic in an output object, called p_value, such as output object a$p_value in a <- ANOVA( ... ).
