sample - sample(sample,3)
works as expected, but it is not a rule.

Is there some way
First, the condition
if (is.na(sample$x[i]== TRUE))
asks if sample$x[i] is equal to TRUE, and then checks whether the result of
this comparison is NA. Because the comparison returns NA when one or the
other argument is NA, this works, but note that it would work as well with
FALSE in place of
Replace your line that updates A with this:
p - unique(c(i,j,1:5))
f - function(x) diag( matrix(x,4,4) )
AA - apply( outer(A,G/B), p[-(1:2)], f ) # form product
A - aperm( array( AA, dim(A) ), order(p) ) # reshape
Here are a couple of tests. You might want to do some
more tests yourself as
