plotFancyCategories: Draw display for discrete predictor in plotSlopes

Description

There's plotFancy for numeric predictor. This is for discrete

Usage

plotFancyCategories(
  newdf,
  olddf,
  plotx,
  modx = NULL,
  modxVals,
  xlab,
  xlim,
  ylab,
  ylim,
  col = c("black", "blue", "darkgreen", "red", "orange", "purple", "green3"),
  opacity = 120,
  main,
  space = c(0, 1),
  width = 0.2,
  llwd = 1,
  offset = 0,
  ...,
  gridArgs = list(lwd = 0.3, lty = 5),
  legendArgs
)

Value

None

Arguments

newdf: The new data object, possibly from predictOMatic
olddf: The model data matrix
plotx: Name of horizontal axis variable
modx: Name of moderator
modxVals: values for modx
xlab: X axis label
xlim: x axis limits. Don't bother setting this, the internal numbering is too complicated.
ylab: y axis label
ylim: y axis limits
col: color pallet for values of moderator variable
opacity: Value in 0, 255 for darkness of interval shading
main: main title
space: same as space in barplot, vector c(0, 1) is c(space_between, space_before_first)
width: width of shaded bar area, default is 0.2. Maximum is 1.
llwd: requested line width, will re-cycle.
offset: Shifts display to right (not tested)
...: Arguments sent to par
gridArgs: A list of values to control printing of reference grid. Set as "none" if no grid is desired.
legendArgs: Arguments to the legend function. Set as "none" if no legend is needed. Otherwise, provide a list
