Hi,
I am running R 3.3.3 and getting the following error:
Error in add_edges(res, edges = t(as.matrix(el[, 1:2])), attr = weight) :
long vectors not supported yet: ../../src/include/Rinlinedfuns.h:138
when passing a 13 GB TransitionLayer object to shortestPath from the
package 'gdistance'.
The error, albeit in a different context, is discussed here:
https://github.com/tidyverse/readr/issues/309
https://github.com/tidyverse/readr/pull/433
However it is not clear to me quite what the fix was and what kind of
limit may still exist in subsequent R versions.
Is this a general problem/issue with R, or is this something more
package-specific which should be addressed on R-sig-Geo?
Cheers,
Loris

This looks to me like a package development issue... which may be under discussion in R-sig-geo (search the archives), but more likely to be appropriate to discuss with the maintainer by email or through their development repository (R-forge, though it looks unused). -- Sent from my phone.

I reported the issue to the developers of 'igraph', which is where 'add_edges' comes from, here https://github.com/igraph/rigraph/issues/255 The response there to the question of whether it is an R core or an igraph issue was R core for sure, but probably both. Is this indeed the case for R core? To my naive eye, the error message suggests more of a known limitation, rather than a bona fide bug.
