Not all of us are familiar with lisp (I have done a little, but not enough to really understand what you are asking). If you tell us what find, member, cond, and loop do, or what functionality you are looking for, then we will have a better chance of telling you how to do the same in R.
Just guessing by the names: The 'which' function may do something similar to 'find'. 'is.element' or '%in%' may do the same as 'member'. 'ifelse' and/or 'switch' may do what 'cond' does. 'replicate', 'lapply', 'sapply', 'while', and 'for' may give the functionality of 'loop'. Those are just guesses based on the names, I don't know what exactly they do, so if I am way off, then tell us what you want them to do. -- Gregory (Greg) L.
