Issue finding S4Vectors during install

[ndaly15]

Hi,

I have come across an issue with installation of the toxpi package. When in a renv environment, it seems to have an issue with finding the S4Vectors package. This for some reason doesn't seem to be an issue if you install the package globally. I tried installing it before installing toxpi package to try to get around this, but it still had issues with finding the S4Vectors package. The only way I could get it to work with renv was to install the S4Vectors package global before installing it in a renv environment.

Is there any way that this could be fixed so I don't have to install any packages globally before installing toxpiR?
