Hello everyone,
I have the following problem with Rstudio, and I can't download any packages. The following error code keeps coming up:
iError in nchar(homeDir) : invalid multibyte string, element 1
In addition: Warning message:
In normalizePath(path.expand(path), winslash, mustWork) : path[1]="C:/Users/Jan W�lfle/Documents"
Can someone Help me ?

What R version are you using? R only supports UTF-8 on Windows since 4.2.0 so if you are using an older version, you need to move your package library to a folder with no non-ASCII characters in its path.
