[R] partial correlation coefficients in R?

[Kaspar Pflugshaupt]

Hello,

after thorough searching of the R help files as well as S+-help, I'm coming
to the list: Is there a possibility to compute partial correlation
coefficients between multiple variables (correlation between two paired
samples with the "effects of all other  variables partialled out")? All I
seem to find are the standard Pearson correlation coefficients (with cor())
and no clue as to how to convert them into partial ones. One of my books
states that"this is a computionally intensive problem and computer help is
most welcome" :-), but fails to give an algorithm. Can anyone help? Maybe
this feature already exists somewhere?

Cheers

Kaspar
