How to identify if a function was called recursivly in R












0















The title says it all.



Example:



f <- function(x, r = TRUE) {

out <- x + 10

if(r) {
out2 <- f(x, r = FALSE)
}
# Here I want something like:
# if(f_was_called_recursively) {
# # only return out
# out
# } else if(!f_was_called_recursively) {
# # return the result from the recursive AND the
# # non recursive calls if an recursive call has been made (if r = TRUE)
# if(r) {
# out <- list("outer" = out, "inner" = out2)
# } else {
# out <- list("outer" = out, "inner" = NA)
# }
# }
# out
}


Problem:
How can I get this f_was_called_recursively?

  • Not too sure what the commented out part does. Are you trying to write a stopping condition for the recursion?

  • No the background is this: f is a function that performs bootstrapping. Sometimes I need to bootstrap from a bootstrap sample, hence the recursion. In essence, I need to output one thing if the “inner” function is called and another for the “outer”
