Hi:
Perhaps this will do; the data were read into a data.frame object named xx.
# Melt the data - constructs a factor 'variable' whose levels are the
variable names
# and a numeric variable named 'value' containing, oddly enough, the numeric
values.
# Requires package reshape.
library(reshape)
library(lattice)
xy <- melt(xx)
# Two versions of the density plot: one with the points as a rug plot, and
another without.
densityplot(~ value, data = xy, groups = variable)
densityplot(~ value, data = xy, groups = variable, type = 'n')
# On the off chance you want a legend....
densityplot(~ value, data = xy, groups = variable, type = 'n',
key = simpleKey(text = levels(xy$variable), space = 'top', columns =
2, lines = TRUE,
points = FALSE))
HTH,
Dennis
