When the Linode is fully powered down, it is possible to resize the partitions as desired.
My earlier notes indicate that atleats 2.5GB of swap space was required to install Rstudio (without docker) in the past, on a machine with 1GB of RAM.
However, by using Docker, I was able to get going with the tidyverse packages, using only 512MB of swap space and the same 1GB of RAM. Of course, some packages like UMAP failed to install. It is yet to be seen whether this is because of the swap.
