[Rd] Hard memory limit of 16GB under Windows?
Hi, I am not not sure whether this topic belongs to this mail list, but I feel the subscribers here should be the right audience. I noticed that the memory limit reported under Windows is 16 GB. I am wondering how to increase it. I didn't found anything in Rprofile.site nor .Rprofile. Is this limit hard coded at compilation? Best, Samuel [[alternative HTML version deleted]]
Hi Samuel,
could you please provide more information? Where do you see the limit
reported or how did you trigger it, what version of Windows do you have,
are you using 64-bit build of R (sessionInfo())
Please check help("Memory-limits") and section 8 of R Admin manual
Best,
Tomas

[Rd] Hard memory limit of 16GB under Windows?
Hi Tomas, Many thanks for your answer. Here is a copy of a fresh session under RStudio, and after a copy under Rgui. Strangely enough the result of memory.limit() is not the same. Without your question I would not have looked to RGui, being used to work with RStudio. The value under RGui sounds to correspond to the total RAM of the computer. It makes me noticing that the value is in MB. The value under Rstudio was so huge (1.759219e+13) that I just interpreted it as GB. But I was totally wrong. So in fact I don't know what it refers to. The documentation says "For a 64-bit versions of R under 64-bit Windows the limit is currently 8Tb.", but it looks like being 16TB, which my computer don't have of course. I still have to understand why my colleague has a problem of memory allocation (cannot allocate vector of size 12.6 Gb). Sorry for the wrong interpretation, but thanks for the help, Samuel --- RStudio R version 3.6.3 (2020-02-29) -- "Holding the Windsock" Copyright (C) 2020 The R Foundation for Statistical Computing Platform: x86_64-w64-mingw32/x64 (64-bit) R is free software and comes with ABSOLUTELY NO WARRANTY.
