When installing a package that is already loaded, RStudio recommends that it save the session and do a shutdown/restart. I usually accept this recommendation. (the reason I do such installs is usually that I have added one or more packages to a list of packages I install in a new project). I find that I often get some message about not being able to save part of my session. As an example, here is the most recent one:
"Error saving session (plots_dir): The system cannot find the path specified"
I did not create and do not consciously make any use of a directory of that name, so I assume it is a default directory of some sort, and I wonder what is causing the error and how to prevent it.
I have had versions of this error four or five more times, and I am still unable to find the problem. Any hints or suggestions would be much welcome. Here is more information on an example where it occurs, including the sessioninfo for this session.
I try to install a package, here fp33. I get an error, shown, and then a dialog box, not shown, asking if I want to restart and assuring me that my data and work will be saved. RStudio then does restart the R session, but says it can not find the path "plots_dir". Note that I did not create a directory of this name and have not created any plots in this session, so I am assuming this is an RStudio problem or something specific to package installation.
Error saving session (plots_dir): The system cannot find the path specified
