Hi
When I call for the loadings of my plsr using the command,
x <- loadings(BHPLS1)
my loadings contain variable names rather than numbers.
>str(x)
loadings [1:94727, 1:10] -0.00113 -0.03001 -0.00059 -0.00734 -0.02969 ...
- attr(*, "dimnames")=List of 2
..$ : chr [1:94727] "PCIList1" "PCIList2" "PCIList3" "PCIList4" ...
..$ : chr [1:10] "Comp 1" "Comp 2" "Comp 3" "Comp 4" ...
- attr(*, "explvar")= Named num [1:10] 14.57 6.62 7.59 5.91 3.26 ...
..- attr(*, "names")= chr [1:10] "Comp 1" "Comp 2" "Comp 3" "Comp 4" ...
Here is the structure of teh data used to conduct plsr
>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] 42.01749.... 40.85915.... 65.01948....
55.98204.... 61.71673.... ...
..- attr(*, "dimnames")=List of 2
.. ..$ : chr "X" "X.1" "X.12" "X.13" ...
.. ..$ : NULL
Because of this I am not able to do a loadings plot
>plot(BHPLS1, "loadings", comps = 1:2, legendpos = "topleft", labels =
>"numbers",
>xlab = "nm")
Error in loadingplot.default(x, ...) :
Could not convert variable names to numbers.
What am I doing wrong
Thanks in advance
