equivalent of $\check Y$ in plotmath

Hi,

I am trying to put the expression which in LaTeX would be $\check Y$  as
a label on the axis of a plot.

How does one get the \check part of the above to produce a similar
symbol in plotmath in R? I looked around plotmath's help but could not
see this in the documentation.

Many thanks for any suggestions, and best wishes,
Ranjan

Whenever plotmath is unable to provide what you want, you can always
go to tikzDevice for native LaTeX support:

Here is an example:

library(tikzDevice)
tikz('test-math.tex', standAlone = TRUE)
plot(1, main = '$\\check{Y}$')
dev.off()
system('pdflatex test-math.tex')


Regards,
Yihui
