Packfor installing2

After an update of R to 4.0.3. and RStudio I cannot install the package packfor (packfor: Forward Selection with permutation (Canoco p.46) version 0.0-8 from R-Forge). Can someone help me? Thanks!

Message in the console:

WARNING: Rtools is required to build R packages but no version of Rtools compatible with the currently running version of R was found. Note that the following incompatible version(s) of Rtools were found:

  • Rtools 3.5 (installed at C:\Rtools)

Please download and install the appropriate version of Rtools before proceeding:

RTools: Toolchains for building R and R packages from source on Windows
Installing package into ‘C:/Users/joachim.deru/Documents/R/win-library/4.0’
(as ‘lib’ is unspecified)
Warning in install.packages :
package ‘packfor’ is not available for this version of R

It looks like you need to update your version of Rtools.

The message in the console was telling me that no compatible Rtools was available, therefore I did not try further.
But you were right, I just had to install Rtools and follow the instructions at

Thank you
