Whenever plotmath is unable to provide what you want, you can always go to tikzDevice for native LaTeX support: http://yihui.name/en/2011/04/produce-authentic-math-formulas-in-r-graphics/ Here is an example:
library(tikzDevice)
tikz('test-math.tex', standAlone = TRUE)
plot(1, main = '$\\check{Y}$')
dev.off()
system('pdflatex test-math.tex')
