There are a few different ways to do this; see the examples in ?plotmath
under the heading "How to combine 'math' and numeric variables".

Hi,
I'd like to make a legend with a mix of mathematical symbol (tau),
numeric variable and character variables.I have tried :
types<-c("Type 1","Type 2","Type 2")
tau<-c(1,3,2)
legend(x="topright",legend=paste(types,"tau=",expression(tau)))
but it doesn't work: the 'tau' symbol is not written in its 'symbol
style' but as 'tau'
Any (good) idea ?
Thank you in advance !
