Hi. Your failure to post in plain text has nearly rendered your example code
unusable. Please post in plain text, not HTML. Also, the ToKeep attribute was
most of your example, yet was completely irrelevant.

When using Rscript, the 'methods' package is not loaded/attached by
default, which it is when you use R. See ?Rscript for details. For
any scripts intended for batch usage, the safest is to only assume
that 'base' is attached, but nothing else.

Ah, this is because you are overwriting your 'A' with each loop. As a
simple way to demonstrate this I changed:
A<-array(, c(maxval,maxval,maxval,maxval,maxval,maxval, 2))
to
A <- list()
and then I changed
A <- sapply((1:Permax),function(p) far(p, i, j, k, l, m,n,
ervalue),simplify=FALSE)
to
