Dear list, Is there any way to use function handle in R? I would like to do something like this (is written in MATLAB) handleFunction=@function1; handleFunction(arguments) # MATLAB knows that handleFunction is related to function1 Thus, handleFunction can be any function, for example: handleFunction=@function1 or handleFunction=@function2 or handleFunction=@function3, etc the function call is always the same handleFunction(arguments) Any ideas? Thanks, Javier

Javier, This can be done very easily in R. In fact every function in R is treated as just another object. Here's an eg. > f1<-function(x) length(x) > f2<-f1 > class(f1) [1] "function" > attributes(f1) $source [1] "function(x) length(x)" > length(f1) [1] 1 > formals(f1) $x So you see you can fetch any parameter of the function using the right function.

Dear Javier Functions in R are just variables like everyone else, so you can simply write: handleFunction=function1 or handleFunction=function2 etc. Have a look into the book by Robert Gentleman http://www.bioconductor.org/pub/RBioinf or the online introduction to R http://cran.r-project.org/doc/manuals/R-intro.html esp. chapter 10. This might save you a lot of time. Best wishes Wolfgang Javier P?rez Florido wrote: > Dear list, > Is there any way to use function handle in R?
