We are currently working on a fix for an issue where R 3.6.0 install.packages() requests are not making use of the package cache provided for rstudio.cloud. It appears that with R 3.6.0 there was a change to the user-agent used when making these requests (see the commit here).
In the meantime, if you choose to use R 3.6.0, the package cache will unfortunately not be used which will lead to your packages being compiled from source, and will likely result in out-of-memory issues for larger package compilations. We apologize for the inconvenience, and will report back here as soon as a fix is in place!
For those wondering how to change R versions, please note the version number in the upper right hand corner. Right clicking will opening a dropdown menu where the version information can be selected:
We just rolled out a change to set the user agent explicitly:
options("HTTPUserAgent" = paste0("rstudio.cloud R (", paste(getRversion(), R.version$platform, R.version$arch, R.version$os), ")"))
This should be widely available in the next 30 minutes or so.
It will take a bit of time to fill the package cache, so there may still be the occasional package build failure due to running out of memory for packages.
