Install R Packages without Opening Power BI in "Run as administrator" Context

Playing around with using R to add visuals to a report, specifically a word cloud. Unfortunately I found that when trying to install packages that did not come with the MRO base install I got "access denied" because the account did not have access to write to the library folder where R was installed. Power BI had to be closed, reopened under the "Run as administrator" context, run at least once with the desired install.package commands and then could be closed and reopened as normal.

It would be helpful to provide a way around this. Alternatively providing a way to provide alternate credentials within the instance of the app already open would be a better experience.
