PROBLEMA CON R4.0 y los paquetes

General
#1

I have a problem with the last update of R, because when installing it together with R studio, I could never install packages like R comander or Reshape2, because I use the command
install.packages ("reshape2")

pero me bota el error :
WARNING: Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding:

https://cran.rstudio.com/bin/windows/Rtools/

alguien me puede ayudar?

I have R studio 4.0 and my goal is to install packages like R comander, reshape2, xlsx and stringr.

but when trying to install with install.packages ("reshape2") it throws the following error in red:

Installing package into ‘C:/Users/FabiánAlvaradoGuevar/Documents/R/win-library/4.0’
(as ‘lib’ is unspecified)
probando la URL 'https://cran.rstudio.com/bin/windows/contrib/4.0/reshape2_1.4.4.zip'
Content type 'application/zip' length 814461 bytes (795 KB)
downloaded 795 KB

package ‘reshape2’ successfully unpacked and MD5 sums checked

The downloaded binary packages are in
C:\Users\FabiánAlvaradoGuevar\AppData\Local\Temp\Rtmp2lar9l\downloaded_packages

It should be clarified that I have already tried to install by tools and I do not get a result, thanks.

You are not showing any error message, just normal installation messages, can you explain what is your problem with this?

#5

yes, it comes out red. Also, when I go to execute the melt function of the reshape2 package it tells me that it cannot be found.

Another way to know that it was not installed correctly is when I run library (reshape2) and the error is as follows:
Error: package or namespace load failed for ‘reshape2’ in get(Info[i, 1], envir = env):
no fue posible abrir el archivo 'C:/Users/FabiánAlvaradoGuevar/Documents/R/win-library/4.0/Rcpp/R/Rcpp.rdb': No such file or directory

The red color doesn't mean it is an error, the package has been successfully installed.

This is your actual issue, R has problems with non-ASCII characters in your windows user name, either change your username or install into the system level package library instead.
