Converts a LaTeX string to a plotmath expression.

TeX(string, output = c("expression", "text", "ast"))

`string`	A character vector containing LaTeX expressions. Note that any backslashes must be escaped (e.g. "$alpha").
`output`	The returned object, one of "expression" (default, returns a plotmath expression ready for plotting), "text" (returns the expression as a string), and "ast" (returns the tree used to generate the expression).

Returns an expression (see the output parameter).

TeX("$\alpha$")
TeX("The ratio of 1 and 2 is $\frac{1}{2}$")

a <- 1:100
plot(a, a^2, xlab=TeX("$\alpha$"), ylab=TeX("$\alpha^2$"))
