I suspect that gcc dies because it runs out of memory since rstanarm installation takes up quite a bit of memory and the RAM gauge in the top right maxes out right before the crash. is there any workaround for this that doesn't involve upgrading my cloud account?

This happens from time to time when a new package version is out, the reason is that the package requires more than 1GB of memory to compile (the current memory limit for the free tier), the way RStudio Cloud addresses this issue is by caching precompiled binaries of the packages but it could take some time for the cache to update to the current package version.

Alternatively, you could try installing a previous version with this command:

remotes::install_version("package_name", version = "x.x.x", repos = '')

thanks. excuse my ignorance but how do we get at the cached version of the precompiled binaries? is it as simple as calling library(rstanarm) once the cache is updated?

You just install as usual with install.packages('rstanarm') but once it's available the binary is going to be used instead of the source code.
