If you know the names will always work (i.e., names of y are always names of
x and the rows always have names) this should do it:
x[!(rownames(x) %in% rownames(y)),]
I.e., those rows of x such that their names are NOT included in the row
names of y.
Hope this helps,

I like to exclude all rows of matrix y from matrix x (like a subset of
x, without y).
The matrix x is of the structure
>str(x)
num [1:346, 1:8] 0.055 0.6833 0.9121 0.0819 0.1223 ...
