In 2.4.0-to-be pie() is happier with plotmath labels, so atop() could have be another solution. In 2.3.1

> pie(c(2,3),labels=expression(pi_1,pi_2))
Error in lab != "" : comparison is not allowed for expressions In addition: Warning message:

is.na() applied to non-(list or vector) in: is.na(lab <- labels[i])

but in the prerelease versions, you get to eat you pie() and have your pi's too.
