I started a course and I managed to download RStudio and to install the package the teacher asked. However, I'm unable to install anything else. I've tried several tips from other asks I saw, but the problem seems to be where it's being installed and not much of a question of CRAN. Here's what happened:
>Error in install.packages : cannot open file 'C:/Users/Anabe/OneDrive/Documentos/R/win-library/4.1/file2910537661eb/stringfish/icelandic_words_500_utf8.txt': Permission denied
I managed to run R as administrator and two packages that weren't being installed before were installed. I do hope everything is going to work now. Thank you so much for your help. I can't wait to learn more R :)
