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
