(showing how functions are constructed out of expressions). [I came too late, Easter Monday is a holiday, here...] Just a short addition: approxfun(.) and splinefun(.) and stepfun(.) or ecdf(.) [after "library(stepfun)"] {{See ?approxfun, etc. for examples}} are very nice examples in standard R how a function can be returned from another function. Actually they show the superiority of R scoping rules which allow an environment (of objects, e.g., numeric variables) for a user created function.
