Hi Jim,

thanks for your reply, but... I can't get that to work either :-(
If I use your example, nothing happens. Only when I start using 
coordinates visible in my *last plot* then the text is visible, and 
only within that last plot... hmmm, I must be missing something obvious 
(I'm still newish to this...)

this is an example of the figures I am trying to add text to:

par(mfrow=c(2,3))
for (i in 1:3) {
plot(log2(RG$Rb[,i]),log2(RG$R[,i]),pch=".")
abline(0,1,col="blue")}
for (i in 1:3) {
plot(log2(RG$Gb[,i]),log2(RG$G[,i]),pch=".")
abline(0,1,col="blue")}

then, anything I try seems to work only for the very last plot of teh series.

Jose
