I''ve read that Vista can *not* be /installed/ under Xen for it checks for ACPI support and install fails if it isn''t present. What if I do the install first from, say, plain Qemu (I''re reused qemu images from Xen) or VMWare (I''ve converted

Hi all, I recently put a new version of my french introduction to R online. It is more specifically targeted at social sciences students and researchers, but could be interesting for beginners who are not really familiar with statistics and coding.
