I tried to install the package plm via install.packages ("plm"). This then ran with many red errors. However, the package could not be found with the library (plm) command. I've already looked for the solution here in the forum. Unfortunately without success.
install.packages("rbibutils", dependencies = TRUE)
install.packages("Rdpack", dependencies = TRUE)
again, it was still unsuccessful.
It would be great if someone could help me.
Thanks in advance
