It also seems to cause problems with some built-in functions:
newlapply <- function (X, FUN, ...)
{
FUN <- match.fun(FUN)
if (!is.list(X))
X <- as.list(X)
rval <- vector("list", length(X))
for (i in seq(along = X)) {
rval[i] <- list(local({
i <- i
FUN(X[[i]], ...)
}))
}
names(rval) <- names(X)
return(rval)
}
newlapply(1:2,log)
#Error in FUN(X[[i]], ...) : non-numeric argument to mathematical function
This seems to be a bug in log() -- this takes local() out of the issue:
f <- function(x, ...) {
+ g <- function()
+ log(x, ...)
+ g()
+ }
f(1)
Error in log(x, ...) : non-numeric argument to mathematical function
It's not following the ... properly for some reason.
But no longer a problem in R-devel -- maybe there is a change worth
back-porting to R-patched.
Best,
