Probability density plot by group

Creates a probability density plot of y for each group of x

Usage

group.pdf(
  x,
  y,
  col = NULL,
  lty = NULL,
  lwd = NULL,
  lx = "topleft",
  ly = NULL,
  ...
)

Arguments

x: Numeric, character or factorial vector of grouping variable (must be same length as y)
y: Numeric vector (density variable)
col: Optional line colors (see par, col)
lty: Optional line types (see par, lty)
lwd: Optional line widths (see par, lwd)
lx: Position of legend (x coordinate or 'topright', 'topleft', 'bottomright', 'bottomleft')
ly: Position of legend (y coordinate)
...: Additional arguments passed to plot
