I'm a novice user of R and am working on a project for which I'm using a package (PupillometryR) that only works with Rtools (I'm working with version 4.2, the latest one) being installed. This works quite well on my laptop, but my supervisor would like me to work in RStudio Cloud. Unfortunately, I cannot find a way to make the cloud environment work with Rtools.
Is this even possible? If so, how? Are there any alternatives?
