Edit Question
Title
Body
Is there a way to compare whether two function objects are the same? m <- mean m == mean ## don't work ## this seems not to be the correct way: functionBody(mean)==functionBody(m) EDIT : Some more details. I have a function with two arguments (a matrix and a user-defined function which is applied columnwise, e.g. mean, median, ...). If the function is mean I want to use colMean instead (to save some running time). foo <- function(m, fun) { #if (fun==mean) { # return(colMeans(m)); #} else { return(apply(m, 2, fun)); #} }
