[Bioc-devel] BiocParallel: windows vs. mac/linux behavior

[Ludwig Geistlinger]

Hi,


I am currently considering the following snippet:


> data.ids <- paste0("d", 1:5)
> f <- function(x) paste("dataset", x, sep=" = ")
> res <- BiocParallel::bplapply(data.ids, function(d) f(d))


Using a recent R-devel on both a Linux machine and a Mac machine, this works fine.


However, on a Windows R-devel this throws:


Error: BiocParallel errors

      element index: 1, 2, 3, 4, 5 ....

      first error: could not find function "f"


Is this a bug or is this related to the different ways in which parallel (for windows here serial) computation is carried out?


Thanks,

Ludwig
