Locally defined S3 methods are not automatically exported (was: function.type are not loaded as global variables)

[Rloveeee]

library("future.apply") plan(multiprocess, workers = 12) test=function(...){ UseMethod("test") } test.numeric=function(x){ return(x) } test.character=function(x){ return(x) } FUN=function(x) { test(x) } xx=future.apply::future_lapply(FUN=FUN,X=c(2,3))

=> It doesn't have test.numeric

I also have another one but I can't (yet) reproduce it on small code. (It can't find roll_sd from RcppRoll).

Best

I suspect this is related to https://github.com/HenrikBengtsson/globals/issues/2 - locally defined S3 methods (contrary to defining them in packages) are not automagically picked up as globals. If this is your problem, you can manually guide the future framework to export them by using:

FUN <- function(x) {
  ## Make sure locally defined S3 methods are found / exported
  test.numeric
  test.character

  test(x)
}

Please cut'n'paste your output so it's non-ambiguous what the problem is. It also help, because by just looking at the output I, or others, might be able to reply must sooner - even without having sit in front of a computer trying to reproduce your problem. Also, make sure to share your sessionInfo() - that always helps when addressing questions/problems.

Also, please try to use Markdown formatting for readability. Below each GitHub comment box there's a link to https://guides.github.com/features/mastering-markdown/ with example how to do that.
