Hi all,
When teaching this year's class, I was quite amazed that one of my examples
didn't work any longer. I wanted to illustrate the importance of
match.fun() with following code:
myfun <- function(x, FUN, ...){
FUN(x, ...)
}
round <- 2
myfun(0.85, FUN = round, digits=1)
I expected to see an error, but this code doesn't generate one. It seems as
if in the current R version match.fun() is added automatically.
I've scrolled through the complete R News section specifying all the
changes and bug fixes, starting from 3.0.0. I couldn't find anything on
that change in behaviour though. Where can I find more information on what
changed exactly?
When you say "current R version", what do you mean? I see an error:
> myfun <- function(x, FUN, ...){
+ FUN(x, ...)
+ }
> round <- 2
> myfun(0.85, FUN = round, digits=1)
Error in myfun(0.85, FUN = round, digits = 1) (from #2) :
could not find function "FUN"
I see this in 3.2.2, R-patched and R-devel.
