If you can provide some reproducible code (small example that yields the problem), that would help. However, you may be experiencing a problem in your PDF viewer (Preview?) due to anti-aliasing, which is noted here: http://cran.r-project.org/doc/FAQ/R-FAQ.html#Why-are-there-unwanted-borders Regards, Marc Schwartz ______________________________________________ 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.
