[Bioc-devel] programmaticallly get unused disk space

Dear list,

I am looking for a way to programmatically get the unused disk space in
R, ideally in a portable way that works on windows/linux/os x.

I have come across OS specific solutions for C (e.g. using statvfs for
linux), but I wonder if I am missing something simpler.

Thank you for any help,
Michael
