Adding Greek letters to LaTeX code while creating documentation for an R package

I'm making a new package for R and I want to include the table generated by the following code in the documentation:

\tabular{cccc}{
sign beta \tab sign gamma \tab K \tab g \cr
+ \tab + \tab 0 \tab -1 \cr
+ \tab - \tab -2pi \tab 1 \cr
- \tab + \tab -pi \tab 1 \cr
- \tab - \tab -pi \tab -1
}


However, I would like the words 'beta', 'gamma' and 'pi' to be replaced by actual corresponding Greek letters. How can I do this? I've tried the following:

$\beta$


and the following:

$\\beta$


but it doesn't work. Any help would be greatly appreciated!

If you wrap it in an equation macro like this \eqn{\gamma} it should work.
