R help - Oct 2007 - Plotting two distance matrices

Hi all,
I'm trying to plot two distance matrices against each other
(74x74,phylogenetic distance and phenotypic distances). However R gives an error
message:"Error in plot.new() : figure margins too large".

Is it because I have too many points to plot?

Thanks in advance,
Muri

No. It *sounds* like you don't have distance matrices but data frames of
distances, because this is the error message that you get. The default
plot of a data frame is a pairs() plot of all columns (variables)
against each other. You will have a data frame if you read in your
distances from an external file (or changed them into data frame). Try
changing your data sets into regular R dist objects, and plot these
against each other (and as.dist really seems to work to data frames
directly):

plot(as.dist(d1), as.dist(d2))

This was only guessing, since the message did not contain sufficient
information.
