Pasting R code lines into labels
Thanks but that's not quite what I meant
I am trying out different functions and they don't necessarily vary in a regular way (like say all being powers of x where it'd be simple to just have a vector for the powers you want)
So I might have
y<-x^2
y<-cos(x)
y<-exp(x+1)
What I am after is a way of running these functions and then calling each one into the labelling for the appropriate graph as I plot it. So then I would have something like
mainlab<-paste("Plot of ",function in question)
...? Thanks Nick

Hi,
See ?plotmath
An example:
x <- 1:10
y <- x^2
plot(x, y, main = expression(paste("Plot of ", y %<-% x^2)))
There are other incantations and examples on the help page above.
