Executing a R-string
m <- c(1,4,2,3,7,5) S <- "which(m==4)" P <- parse(text=S) R <- eval(P) R Before you do this, see fortune(106)
fortune(106)
If the answer is parse() you should usually rethink the question.

Hello... In other languages (e.g. php, perl), you have the ability to create a valid string and execute the string to get the result. For example (in pseudo-R): S<-"which(m==4)" R<-exec(S) I know this does not work, but was wondering if there was an equivalent mechanism that I cannot find in the docs anywhere to make it work. Thanks, Joe
