Dear All,
I'm running into issues with calling mccollect on a list containing NULL
using R 3.6 (this used to work in 3.5.3):
jobs <- lapply(
list(NULL, 'foobar'),
function(x) mcparallel(identity(x)))
mccollect(jobs, wait = FALSE, timeout = 0)
#> Error in names(res) <- pnames[match(s, pids)] :
#> 'names' attribute [2] must be the same length as the vector [1]
Note, setting a "name" for the jobs does not help, but the above works with
"wait=TRUE", and also if I change the order of NULL and "foobar", although
in that case, the second value (NULL) is ommitted. It also works with
mclapply fine.
Any ideas/suggestion on how to get mccollect work with the above example?.
NULL is not a valid job identification. Perhaps mccollect() could give a
clearer error message, but I don't see, given its documentation, what
else than throwing an error it should do. What is the problem you were
trying to solve?
Best
Tomas
Thanks,
