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 ma...

...ear all, i'm using gdistance to model animal movement across landscape. I have imported 11 rasters with roads, freeways, slope, use-of-land, lakes (...) after recoding them with GRASS with a HSI value ranging from 1 to 4. I've assigned zero to the NAs and then transformed all the rasters in TransitionLayers (function=mean,directions=4) and later summed all of them into a new transition: > MY_transitionclass : TransitionLayer dimensions : 2181, 1648, 3594288 (nrow, ncol, ncell) resolution : 100.0049, 99.98945 (x, y) extent : 1460708, 1625516, 4947383, 5165460 (xmin, xmax, ymin,...
