| findGlobals {codetools} | R Documentation |
Finds global functions and variables used by a closure.
findGlobals(fun, merge = TRUE)
fun |
function object; usually a closure. |
merge |
logical |
The result is an approximation. R semantics only allow variables
that might be local to be identified (and event that assumes no use
of assign and rm).
Character vector if merge is true; otherwise, a list with
functions and variables character vector components.
Character vectors are of length zero For non-closures.
