[TxMt] problem with R interaction [was math bundle feature request]

[Peter Cowan]

If I'm not mistaken to use commands for the console grammer the line
needs a leading greater than symbol and space "> ".  Doing so gives me
the correct answer, the command also inserts this on the next line
which is why you see the trailing greater than symbol.

e.g:
> 100^2
[1] 10000
> 1/1e-1
[1] 10
>

See also the help file in the R bundle.
