Hi, I need some neat ways of determing a subset of binary strings. For example, x=c(0,0,1), y=c(0,1,1), z=c(0,1,0). So x is a subset of y and z is also a subset of y, but x is not a subset of z. I tried to search R functions and packages but no hits. Any ideas?
Hi. Try this all(x <= y) # [1] TRUE all(z <= y) # [1] TRUE all(x <= z) # [1] FALSE Hope this helps. Petr Savicky.
