title: R custom package install from file error
body: <p>I've been working on a R package for a simulation project, on my computer at home I've used RStudio to build and install it successfully. However on another machine at university I'm having trouble... If I try and build a binary in RStudio, which also installs it too, I get an error, If I just compile a source to get a .tar.gz it works, but then when I come to install I get the error again. The readout with error that occurs both times, is below. I think it has something to do with libraries, but why this would be different to my home computer I would not know, I'm no programmer, and installed R and RTools and RStudio in exactly the same way on this machine as on my personal machine. - I have admin access for a few days.</p>
