[R] Legend

>a <- .33
>b <- .55
>legend("bottom", fill=c("red","blue"),
>  legend=c(bquote(p == .(a)), bquote(p == .(b))), bty="n")

paste should do it:

legend("bottom", fill=c("red","blue"),
  legend=paste("p=", c(a,b), sep=""), bty="n")

and would be even easier if a and b were already in a vector.

> However what I want is that : the value "0.30" should be a value of a variable instead of a constant, so that I can put the name of this variable and in legend it's value will be displayed. Can anyone tell me how to do that?
