The problem is here:
> A <- c(pls[1],pls[2],pls[3],pls[4])
> B <- c(pls[5],pls[6],pls[7],pls[8])
This creates lists A and B, not data frames.
Either use cbind() instead of c(), or simply say
A <- pls[,1:4]
B <- pls[,5:8]
The the rest should work.
Btw. it is probably a good idea to avoid single-character names for
variables. Especially c and C, because they are names of functions in R.
