[R] PCA with NA

[Birgit Lemcke]

Dear all,
(Mac OS X 10.4.11, R 2.6.0)
I have a quantitative dataset with a lot of Na´s in it. So many, that  
it is not possible to delete all rows with NA´s and also not  
possible, to delete all variables with NA´s.
Is there a function for a principal component analysis, that can deal  
with so many NA´s.

Thanks in advance

Birgit
