A) You are repeatedly referring to RStudio... if you have a problem with RStudio, it is off-topic here and most people won't know how to fix it. RStudio occasionally gets out of sync with R and (the majority of us) don't keep track of that status here.
Assuming the problem is with R (you confirm this by using R or RGui directly and seeing the same errors)... B) When the R error messages say they cannot find the index, then that means you either have the wrong CRAN mirror URL (there is a whole list of them you can try) or there is some kind of network storm that will blow over if you try again later. C) Finally, Rtools is not an R package... you will never succeed installing Rtools using install.packages. Use your web browser to look on CRAN for Rtools42 software and download the corresponding Windows setup program and run it. You should read and follow the instructions [1]. I am pretty sure you will need to re-start R so it will find Rtools.
