Thanks David, for helping out. Works great. A question about your added lines of code:
with opar <- par(mar=c(8,3,2,2)) your are setting the margins, and you store them in opar next, par(opar) does nothing, I think because it just sets the same margins again. shouldn't this be something like the following: opar <- par( 'all graphics parameter') # store all current graphic parameters (in correct R language of course) par(mar=c(8,3,2,2) # set new margins barplot(...) par(opar) # restore former graphics parameters.
