Dear Stephen, You need to print() the plot explicitly. This is FAQ 7.22 (http://cran.r-project.org/doc/FAQ/R-FAQ.html#Why-do-lattice_002ftrellis -graphics-not-work_003f)

I would be happy to send this off list. I am sure that I am missing something simple. The plotting works if I just paste the call to qplot into R and replace the [i] with a number. Thanks for all of your help in advance. #loop to spit out PDFs list.names <- as.character(unique(braggxsec[,"Creek"])) for(i in 1:length(list.names)){ pdf(paste("~/Desktop/base_pdf_xsec/", list.names[i], ".pdf", sep="")) qplot(measurment_num, value , data=subset(braggxsec.melt, Creek==list.names[i]), colour=variable, geom="line", xlab="meters across the channel", ylab="meters from bankfull", col="black", linetype=variable, main=list.names[i])+facet_grid(station~Creek)+scale_y_reverse(breaks=bre aks)+scale_x_reverse()+theme_bw()+ opts(panel.grid.minor = theme_blank(), panel.grid.major=theme_blank()) dev.off() } -- Stephen Sefick Let's not spend our time and resources thinking about things that are so little or so large that all they really do for us is puff us up and make us feel like gods. We are mammals, and have not exhausted the annoying little problems of being mammals. -K.
