Re: [igraph] R: Export the operator '%--%' for use with 'foreach'

[Chris Watson]

Yes, I tried that. It works without issue on Linux, but I see the same error message on a Windows machine. The line is specifically:

x[vs] <- foreach (i=seq_along(vs), .combine='c', export="%--%") %dopar% {

The "export" argument is not needed on Linux.

(This isn't a priority for me as I found a workaround using slightly different code)

Did you try just supplying it as a string? This works in R in general:

"%foo%" <- function(a, b) a + b
21 %foo% 21
#> [1] 42
