R Core Team-- Would it be reasonably easy for the function "sub" be given its own bookmark in the next edition of the R Reference Manual? I could not remember the name of any R function to do substring substitution, and it was not easy to find. It does appear in the index, but not in the bookmarks, nor under "*Topic character". By the way, let me express my appreciation for the *Topic entries in the RRM index. They are the closest I've found to any taxonomic listing of R functions and have saved me a lot of looking around. Not to be churlish, but rather for the record, the major R reference books I have (Verani, V&R 4, Maindonald & Braun, S Prog) are rather thin on index entries under "character" or "string". I realize that if I already knew the answer, I could have found it, easily, but I didn't, and it was not easy. THANKS for considering it. -- Mike Prager, NOAA, Beaufort, NC * Opinions expressed are personal and not represented otherwise. * Any use of tradenames does not constitute a NOAA endorsement.
