The phrase "quoted string" in my mind is redundant.
It is also inaccurate, after all you could do the following:
tmp <- paste(letters[ c(12,19)], collapse='') system(tmp,show=T)
here tmp is a string and works, but quoting it would break things. Greg Snow, Ph.D. Statistical Data Center, LDS Hospital Intermountain Health Care greg.snow at ihc.com (801) 408-8111
