[R] conditioning inside an lapply

[markleeds at verizon.net]

This is probably basic but I want to condition based
on the name of the component inside an lapply.

So, in the simple example below, if .elem was x
i want to do one thing but if it's y a
different thing etc. Can someone tell me
how to do that without using names(temp)
as the thing one sends into the lapply ?
Thanks.

temp <- list(x=2,y=3,x=4)

invisible(lapply(temp, function(.elem) {
       print(.elem)
     }))
