While doing pls I found the following problem

> BHPLS1 <- plsr(GroupingList ~ PCIList, ncomp = 10, data = PLSdata, jackknife = 
>FALSE, validation = "LOO")

when not enabling jackknife the command works fine, but when trying to enable 
jackknife i get the following error. 



>BHPLS1 <- plsr(GroupingList ~ PCIList, ncomp = 10, data = PLSdata, jackknife = 
>TRUE, validation = "LOO")
Error: cannot allocate vector of size 289.1 Mb

I am dealing with a very large dataset

>str(PLSdata)
'data.frame':   40 obs. of  2 variables:
 $ GroupingList: int  1 1 1 1 1 1 1 1 1 1 ...
 $ PCIList     : AsIs [1:40, 1:94727] 0 0 0 0 0 0 0 0 0 0 ...
  ..- attr(*, "dimnames")=List of 2
  .. ..$ : chr  "X" "X.1" "X.12" "X.13" ...
  .. ..$ : NULL

>object.size(PLSdata)/1048600
28.9113560938394 bytes

How can i get around this memory shortage
