plotFancyCategories function

Draw display for discrete predictor in plotSlopes

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

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
)

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

Returns

None
