I've started to re-use R through RStudio, and I've not used it for a while. For some reason, I'm having trouble installing tidyverse and a number of other packages. In my previous experience, this was such a simple task. I just reinstalled the latest version of RStudio and it doesn't seem to help.
The problem seems to be that I have a non-zero exit, and that a lot of the dependent packages are not available. Ì get text such as the following as well.
Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding:
       binary source needs_compilation
cli     1.0.0  2.0.2             FALSE
rlang   0.2.0  0.4.5              TRUE
pillar  1.2.1  1.4.3             FALSE
Any advice on where to start?
