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
