I am quite new to R and and have only been introduced it quite recently at university. I have just installed Rstudio on external hard drive since my macbook did not have enough disk space however I cannot seem to change download location of any of Rstudio's packages. I wish to for example load data from excel..however I am unable to do this as I need a particular package to do so. Thus I seem to be stuck..is it at all possible to download studio packages externally?
Apologies.if this seems like a trivial question.
