R help - Nov 2008 - Boxplots with different variables and different ranges in R

Dear all,
 
I am trying to make boxplots in one diagram but it is not working. Actually I
have a large dataset, around 35 water quality variables with different units and
of course in different ranges (some are orders of magnitude bigger than others).
I want to produce one diagram with all the boxplots of the variables of my
dataset.
 
I tried these series of commands:
>oldpar <- par(mfrow=c(1,ncol(R)))
> invisible(apply(R, 2,boxplot))
> for (i in 1:ncol(R)) boxplot(R[,i], main=colnames(R)[i])
> par(oldpar)
(where R is the name of my dataset)

The problem is that after the second command, there is an error in plot.new( ):
figure margins too large.

Is there a way to overcome this and put all my variables in a same diagram? I
tried with less number of variables, but I had the same warning.

Thank you very much for your time and help.

Kind regards

Maria Lathouri

We need to have some idea of what the data looks like and what code you have
been trying to make any sensible suggestions.

Can you supply a small example ?
