Codetools Query (repost)
Sorry for reposting, i keep forgetting this should be plain text.
Will not make this mistake again
Hello,
The following code
moo <- function(a=1){ x=1; x=x+y}
funs <- new.env()
enter <- function(type, v, e, w){
assign(v, TRUE, funs)
}
library(codetools)
collectUsage(moo, enterGlobal = enter)
adds + to the environment funs i.e.
funs: "=" "{" "+" "y"
How can i ignore variables which are present in base, utils, stat
environments from being added (equivalently(?) symbols present in R
when R is started)
I tried
funs...
