R help - Apr 2002 - column-plot of rainfall data

Hello,

I have some daily rainfall data from rain gages. E.g.:
date       p1   p2   p3
20/04/2002 10.2 8.6  6.3
21/04/2002 0.4  1.6  1.4
22/04/2002 0.2  0.0  0.4
23/04/2002 5.2  1.0  0.2

I'd like to plot them in a column plot by day, to be able to
compare them. I made an example in exell, that I attached, but
can't find out how to do it in R. The data vector is a POSIXct.

Thanks,

Something like this:

rain <- read.table("rain.txt",header=T)
barplot(t(as.matrix(rain[-1])),
        names.arg=as.character(rain$date),beside=T)
