[R-SIG-Mac] ‘package ‘XML’ is not installed for 'arch=x86_64'’

[Ricardo.Julio.Rodriguez.Fernandez at sergas.es]

Hi,

I'm trying to confirm I understand how packages are installed and manage in R to be able to better interpret error/warning messages.

In a Mac OS X installation of R I get this error:

> require(XML)
Loading required package: XML
Failed with error:  ‘package ‘XML’ is not installed for 'arch=x86_64'’

But the graphical interface R Package Installer says that version 3.9-4 is installed.

Please, where am I wrong? Thanks!
