I'm using R matrices to use an R program and then do things with it in
Sage. For some reason Sage doesn't get the "right" answer for
matrices above a certain size.
The first one is right (it gives the space that is in the returned
string) while the second one makes no sense; ZZ='' is what actually
comes back. But there is no real reason for this - what's special
about the length? - and doing these in Sage's r_console() gives normal
results for the matrix.
So I feel like pexpect must be doing something naughty. Does anyone
have any ideas what might be going on so I can use more data?
Thanks,
