Hi:

I'm having some difficulty properly subscripting a function to remove
complete NA rows from a R array object.  Could someone please suggest how
best 
to script this out?

Data structure:

X is an array with 3 dimensions (replicates, Species, Sites)
replicates: 1 to 6 but ragged...not all sites equal



,,Site1

	Sp1	Sp2	Sp3...	Sp50
1	5	4	3		2
2	3	0	0		1
3	NA	NA	NA		NA
4	NA	NA	NA		NA
5	NA	NA	NA		NA
6	NA	NA	NA		NA



,,Site2

	Sp1	Sp2	Sp3...	Sp50
1	5	4	3		2
2	3	0	0		1
3	1	1	0		0
4	NA	NA	NA		NA
5	NA	NA	NA		NA
6	NA	NA	NA		NA


,,Site3

	Sp1	Sp2	Sp3...	Sp50
1	5	4	3		2
2	3	0	0		1
3	1	1	0		0
4	5	4	3		2
5	3	0	0		1
6	1	1	0		0

Most appreciatively:

Brian Campbell
