The library PVCA can (at least partially) do this: unfortunately, AFAIK, only variation due to categorical variables can be analyzed (thus not continuous ones).

Subject: [BioC] Estimate how much a factor contributes to the variation
I'm analyzing a microarray data set with three factors; cancer (yes or no, the interesting one), age and % tumour cells in sample.
I'm interested to know how much each factor/coefficent is able to describe the overall variation in the data set.
My googlefu turns up little of interest, could someone suggest a suitable package or some key words that could take me further?
