[R] math symbol + value of a variable in legend.

[Kenneth Roy Cabrera Torres]

Hi R users:

I will like to have a legend with math symbols and also with
the value of a variable.

But I cannot obtain both at the same time (symbol + value of a
variable):

Here is a reproducible example:

m1<-5
m2<-12
plot(1:5,1:5,type="n")
legend("topleft",legend=c(paste(expression(mu),"=",m1),expression(paste(mu,"=",m2))),lty=1:2)

Thank you for your help.

Kenneth
