subset in a BIG matrix
I have a matrix with a lot of values inside..
when I execute the folowing command
matrix2=subset(martix, condition.....)
it works...
but after the previous command I execute another "subset"
matrix3=subset(martix2, condition2.....)
and appears the following error:
(subscript) logical subscript too long
How can I solve this???
I think the probles is the size of the matrix...

(for type = t2)
name type
B t2
F t2
Thanks
