Check out the language reference manual in the directory .../R/rw2001/doc/manual/r-lang.pdf . On Windows its also accessible from R via Help | Manuals | R Language The manuals can also be found online. e.g. Google for r-lang "infix and prefix" to find the relevant section. By the way, even without this problem seq is better than : in programs as it has better boundary behavior. Consider 1:n vs. seq(length = n). For n=0 the : operator actually generates the vector c(1,0) whereas the seq solution gives a zero length vector, as desired. Even seq has problems unless you use length= . The : operator is mainly useful if you are typing throwaway code directly into R. ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
