[R] PCA reconstruction funtion

[Poizot Emmanuel]

Dear all,

I did performed a PCA analysis (using prcomp function) on a data matrix. 
Then I would like to reconstruction part of the original data set using 
only specifics and choosen  eigenvectors.
I would like to know if there is a function under R witch can perform 
this reconstruction.
Regards
