Hi, Whats the easiest way to set a desired interval for tics on axes in R ? And will the 'grid' command put gridlines on all tics automatically ? I tend to get stuck with graphs with ranges 0-1 with only 2 tics and 2 gridlines in the 0-1 range, while I would like 10 tics (or every 0.1) tnx, Piet please reply to pvremortNOSPAM at vub.ac.be
