If you use install,packages() from within R there is a lib argument. I
do not use RStudio so not sure how it works there.

That is really a statistical question not one for this list but the

Dear Meriam
Your csv file did not come through as attachments are stripped unless of
certain types and you post is very hard to read since you are posting in

Dear Rachel
Not sure if this is going to help but if it is a csv file then

If I understand you correctly you have a very large sample size so it is
not surprising that you get very small p-values. Eevn a scientifically
uninteresting difference can become statistically significant with large
