segfault issue with parallel::mclapply and download.file() on Mac OS X
I have an lapply function call that I want to parallelize. Below is a very
simplified version of the code:
url_base <- "https://cloud.r-project.org/src/contrib/"
files <- c("A3_1.0.0.tar.gz", "ABC.RAP_0.9.0.tar.gz")
res <- parallel::mclapply(files, function(s) download.file(paste0(url_base,
s), s))
Instead of download a couple of files in parallel, I get a segfault per
pro...

...s API is very restricted, though, so I suggest to look at
the curl package.
