Dear Sirs,
I am a new user of the R package. When I try to use the curve function it
confuses me.
> curve(x^2)
Works fine.
> curve(x)
Makes a complaint I don't understand. Why is x^2 valid and x is not?
I check the documentation of curve, and it says the first argument must be
an expression containing x.
> expression(x)
Is an expression containing x.
> curve(expression(x))
Makes a different complaint and mentions different lengths of x and y (but I
use no y here).
I understand that plotting the function y(x) = x is rather silly, but I want
to know what I am doing wrong, for the sake of my understanding of how R
works.
Thank you for support.
Abhilash B.
