PlotDist: Side-by-side box plots, for a numerical variable, grouped by...
In otvPlots: Over Time Variable Plots

Description Usage Arguments Value License Examples

For a variable is all positive (no zeros) and has larger than 50 all distinct values, if it is highly skewed, then all box plots can be plotted under the log base 10 transformation. See the argument skewOpt for details.

1	PlotDist(dataFl, myVar, dateGpBp, weightNm = NULL, skewOpt = NULL)

`dataFl`	A `data.table` of data; must be the output of the `PrepData` function.
`myVar`	The name of the variable to be plotted
`dateGpBp`	Name of variable the boxplots should be grouped by. Same options as `dateGp`. If `NULL`, then `dateGp` will be used.
`weightNm`	Name of the variable containing row weights, or `NULL` for no weights (all rows receiving weight 1).
`skewOpt`	Either a numeric constant or `NULL`. Default is `NULL` (no transformation). If numeric, say 5, then all box plots of a variable whose skewness exceeds 5 will be on a log10 scale if possible. Negative input of `skewOpt` will be converted to 3.
