R help - Nov 2007 - print matrix content on plot

Hi,
 
I saved as a matrix a summary of a PCA analysis and I've used barplot to
plot the PCA variances. I would like to print on the same graphic the values of
my matrix m1 - in other words the summary of my PCA analysis. I can do it very
painstaking with text for each row and make sure that everything aligns and so
on but i wonder if there is a better method than that.
 
My summary follows:
 
m1
 
                                     PC1      PC2         PC3       PC4

The textplot function in the gplots package may be of help.
