I'm not sure I'm following you but have you tried,
identical(matrix(c(1,1,1,1),ncol=2), matrix(c(1,1,1,1),ncol=2))
?all.equal
?isTRUE
?identical
and possibly the compare package,
compare(matrix(c(1,1,1,1),ncol=2),matrix(c(1,1,1,1),ncol=2))

I'm trying to compare two matrices made up of bits.
doing a simple comparison of
matA == matB
yields this sort of output.
[,1] [,2] [,3] [,4] [,5] [,6]
[1,] FALSE TRUE FALSE TRUE TRUE FALSE
[2,] TRUE TRUE TRUE TRUE TRUE TRUE
[3,] FALSE TRUE FALSE FALSE FALSE TRUE
[4,] FALSE TRUE TRUE FALSE FALSE FALSE
[5,] TRUE TRUE TRUE TRUE FALSE FALSE
[6,] TRUE TRUE TRUE TRUE FALSE FALSE
I really would like just one comprehensive value to say TRUE or FALSE.
This is the hack (rather ugly I think) I put together that works,
but there has to be a nicer way, no?
res=pop[1:ROWS,] == keep[1:ROWS,]
if ((ROWS*COL) == sum(res))
{
cat('they are equal\n')
}else
cat('they are NOT equal\n')
Thanks!
