Install package CHAID is throwing error saying package or namespace load failed for 'libcoin'

Hi, when I try to install CHAID using - install.packages("CHAID", repos=""), it is throwing me the following error:

It seems you are missing the mvtnorm package, try installing it first.


Also, you have the 32-bit R version installed, if you don't actually need this version (which is rare this days), I recommend you to uninstall it to avoid having to compile packages for two architectures unnecessarily.
