[R] looking for a plot function

[Doran, Harold]

If your data were in the long format you could use interaction.plot.
But, I think trellis plots in lattice are much better than this
approach.

Subject: [R] looking for a plot function

Dear useRs,

I have a data frame and I want to plot all rows. Each row is represented
as a line that links the values in each column. The plot looks like
this:

dfr <- data.frame(A=sample(1:50,10),B=sample(1:50,10),
	C=sample(1:50,10),D=sample(1:50,10))
xa <- 10*1:4
plot(c(10,40),c(0,50))
for (i in 1:nrow(dfr)) {
	lines(xa,dfr[i,],pch=20,type="o")
	}

Things get more complicated because I want the columns to be rescaled so
as to fit nicely on a graph (for example if A has values between 0 and
100 but B has values between 100 and 1000, then rescale A or B), labels
etc. Is there a function that can do plots like this? 

Thank you,
b.
