Subject: [R-sig-Geo] strange issue of memory converting a raster to a data
frame
Dear list members,
In converting a raster as the one below to a data frame, I have an issue of
memory allocation only when I use a specific pc, and in particular the one
with more memory. To be more precise (using same version of R 4.2.2 and
Terra terra 1.6.47, by means of as.data.frame() function):
with a I5 processor with 8Gb of memory, windows 10 it works
with a I7 processor with 16gb of memory, windows 11 it doesn't
I'm not able to figure out a possible explanation!
Any suggestions on what to check?
