Thanks, Deepayan. I was rather hoping that I could do something with environment variables and the Makefile, along the lines of removing the .tex files created from the .Rnw files and recreating them when I switched the final output from D.pdf to H.pdf. This would probably also require touching a file name in the directory to keep track of whether the figures were black and white or color. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
