Error: vector memory exhausted (limit reached?) R 3.5.0 macOS

Question

I\'ve been working for a while with a number of large files containing gene expression data, and I\'ve recently run into an issue with loading that data into R, after upgrad

Answer 1

A solution for those who might be unfamiliar with the command line can be found here:

In short, the solution is to use the usethis package.

usethis::edit_r_environ() will open the .Renviron which is in your home directory. This .Renviron affects all Rstudio work

usethis::edit_r_environ("project") will open an .Renviron local to your project. Changes made to this file only affect work done in that particular Rstudio project.

Once open, the R_MAX_VSIZE var can be set.

The linked page also links to this blog which describes R's startup process in great detail.
