Hi,
until now I’ve played around with the online version of MetaboAnalyst and it works well. But since I’d like to dive a bit deeper into the data, an installation of the R program would be of great use. Unfortunately, I’m new to this language and thus even the installation seems to be problematic. I’ve installed Rtools and Rbase (4.2.0). Option 1 is using the metanr_packages. This I assume I run in RStudio and once the function is run and metanr_packages() is run as well the following message pops up:
'getOption("repos")' replaces Bioconductor standard repositories, see '?repositories' for details
replacement repositories:

I have simply no idea what to exactly do at this point, so I tried Option 2, which is using the pacman package, which leads to the following message:

This all seems pretty frustrating and any advice on how to get this to run would be greatly appreciated.
Thanks so much, 
Ilja
