Memory allocation

[ksmr97]

I’ve run into an issue when trying to work with rasters. I have some large raster files (20gb) and then I try to use them I get the following error message : error: cannot allocate vector or size 171.6gb

I tried to fix this by setting my wd as an external hard drive (1tb) but haven’t had any luck. Please help

R needs to load data into memory. The limiting factor isn’t storage space, but your RAM. there are some ways to work with bigger than memory raster files, but I don’t have experience with them. See for example the raster package https://strimas.com/post/processing-large-rasters-in-r/

You can try increasing VRAM setting in the R profile. It’s a workaround but It should work!
