[R] problem with pls(x, y, ..., ncomp = 16): Error in inherits(x, "data.frame") : subscript out of bounds

[ryszard.czerminski@pharma.novartis.com]

When I try to use ncomp parameter in pls procedure  I get following error:

> library(pls.pcr)
> m <- pls(x, y, validation = "CV", niter = 68, ncomp = 16)
Error in inherits(x, "data.frame") : subscript out of bounds

Without ncomp parameter everything seems to work OK

> dim(x)
[1]  68 116
> dim(y)
[1] 68  1
> m <- pls(x, y, validation = "CV", niter = 68)
> length(m$ncomp)
[1] 67
