Hi, How do I tell an if statement to generate two seperate outputs. E.g If X>5 I want to create df1 and df2: if (X>5) {df1<-c(4,5,6,7,8) AND df2<-c(9,10,11,12,13)} Thanks, James -- View this message in context: http://www.nabble.com/If-statement-generates-two-outputs-tp22650844p22650844.html Sent from the R help mailing list archive at Nabble.com.

Maybe there is a great website out there or white paper that discusses this but again my Google skills (or lack there of) let me down. I would like to know the best way to export several doubles from a function, where the doubles are not an array. Here is a contrived function similar to my needs: multipleoutput<-function(x) { squared<-x^2 cubed<-x^3 exponentioal<-exp(x)

...on how to do this the  "normal" R way, so let's go ahead and use the "return a list" method  (I think it's better than using the `c(squared=x^2, cubed=...)`). Here's an interesting way to receive the assignments. Check out this  function: http://code.google.com/p/miscell/source/browse/rvalues/rvalues.r With that ':=' function loaded, you could do this: ============ multipleout <- function(x) {    list(squared=x^2, cubed=x^3, exponential=exp(x),         factorial=factorial(x)) } c(sq,cu,ex,fa) := multipleout(1:3) show(sq) [1] 1 4 9 show(cu) [1]  1  8...
