Probability density plot by group
Creates a probability density plot of y for each group of x
Usage

y,
col = NULL,
lty = NULL,
lwd = NULL,
lx = "topleft",
ly = NULL,
...
)
Arguments

- 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')
