Matt's suggestion works in Linux (I use Ubuntu and Debian variants), but I
haven't yet
been able to get it to work in Windows. In a DOS terminal, I can run Cygwin's
blas.exe via
blas -c "read -t 1 -n 1"
and get the right functioning, but when embedded in R in various ways, I get
several error
messages that imply R is not finding or interpreting the command correctly.
As the details are arcane, please contact me off-line, and I'll report back to
the list
when we have a solution.
However, if someone could try Matt's suggestion on a Mac and let me know
outcome, that
would be helpful. Since .Platform allows me to determine OS type, I should be
able to work
out a more or less platform-independent function.
