[R] plot 7 * 3 matrix on DIN A4 pdf

[stefan.duke at gmail.com]

Hello,

I want to plot 21 scatter plots in a 7*3 matrix on a single A4 page
(using mfcol). Below is an example, which -by and large- looks very
close to the desired result. But I do not get it to fill out the whole
page. If I specify the a different page size, the plots still do not
fill out the whole page.
Anybody an idea what to do? Maybe adjusting indvidiual plot size (if
so, how?). Or is there a neater command to create a matrix of
individual plots
Best,
Stefan
