plotting lines with missing data for x values

Remove duplicates from a data frame but with some special requirements
Hi all. So I have a data frame with multiple columns/variables. The first variable is a major sample name for which there are some sub-samples. Currently I have used the following command to remove the duplicates: Samps_working<-Samps[-c(which(duplicated(Samps$ESR_Ref_edit))),] This removes all of the duplicated sample rows. However, I just realised that, of course, this removes the first

mtext problem - grainy and massive file size
Hi Team, I'm on a mac, 0SX 10.5.6, R 2.7.2. I consistently make pairs plots and use mtext() to put labels on top of the plot in the outer margin. All of a sudden, this text has become really grainy in the final product and is making huge files. I have no idea why this has just started happening. The only thing I've done lately is install the new version of GIMP and run the script to
