Hi,

I believe this question has been asked before, but I cant find and don't remember the answer.

The problem is simple, calling 'plot.data.frame(x)' gives a nice 'matrix of scatterplots' for each pair of columns in x. for example;

x <-

data.frame(a=jitter(01:20), b=jitter(20:01), c=jitter(21:40), d=jitter(rep(01,20)), e=jitter(rep(10,20)), f=jitter(rep(20,20)) )

plot(x)

gives a 6 by 6 grid of scatter plots, two (upper right and lower left) for each pair of columns in x. (I am going over these basics so that you can understand what I mean next).

I would like to see just part of the above result, namely the nine plots in the top right of the given plot, or;

a vs. d | a vs. e | a vs. f b vs. d | b vs. e | b vs. f c vs. d | c vs. e | c vs. f

I tried a number of ways to do this, but I can't find either the right formula or the right function to get what I want.

Any suggestions you can give (especially any not involving the source code of 'pairs') are most welcome.

Dan.
