multijitter function

Wrapper around jitterp that plots multiple jitter plots on the same plotting device (analogous to violins())

multijitter(
  x,
  data = NULL,
  group = NULL,
  horiz = FALSE,
  order = NULL,
  xlab = "",
  ylab = "",
  col = "black",
  pch = 16,
  spaces = "_",
  width = 0.1,
  xlim = NULL,
  ylim = NULL,
  add = TRUE,
  ax = FALSE,
  srt = 45,
  adj = c(1, 0),
  ...
)

Arguments

• x: plotting statistic (numeric vector) or formula object from which a plotting statistic and grouping variable can be extracter (i.e. of form x~group)
• data: data.frame object containing x and y
• group: grouping variable
• horiz: logical indicating whether to plot horizontally
• order: order of factor levels of categorical factor
• xlab: x axis label
• ylab: y axis label
• col: vector of border colors
• pch: vector of symbols
• spaces: character string in group to replace with spaces for labels, if not NULL
• width: standard deviation for jitter
• xlim: x limits (data limits used if NULL)
• ylim: y limits (data limits used if NULL)
• add: logical whether to add to existing plot (default: TRUE)
• ax: whether to plot axes
• srt: angle for categorical axis text rotation
• adj: adjustment for axis labels (defaults to c(1,0), i.e. top right)
• ...: other arguments to pass on to jitterp() and plot()

Examples

data.frame(p=rnorm(50), cat=rep(c("A","B","B","B","B"),10))->d
multijitter(p~cat,d, add=FALSE)
