Installing package into ‘C:/Users/mvict/OneDrive/Documentos/R/win-library/4.0’

Warning in install.packages :
unable to access index for repository https://cran.rstudio.com/src/contrib:
To avoid all this mess, next time post the output as formatted code (that will avoid the one link per post limitation).
About your problem, this seems like a connectivity issue, R is not being able to connect to the CRAN repository you have selected, these are some things to try.
Choose a different CRAN repository, RStudios repository is a good choice (http://cran.rstudio.com/) or you could choose one that is geographically closer to you.
Check if your internet connection has traffic restrictions of some kind, like a firewall, proxy server, etc. This is usually the case when you are at work or school.
Thank you for the help.
Excuse me but could you tell me, where to find the options menu? It isn't in File, isn't it?
I will start looking there.
Furethermore I know that my antivirus is cutting some connections like in the Firewall. I had tried to install the package disconnecting the antivirus but it didn't work.
