[R] Deriv and integrate

[tlorino@vet-alfort.fr]

 Dear R users,

I would like to express a function (with only one argument) as the integrate of its derivate.
For example, for y=x^2, I would like something like

integrate(deriv(~x^2,"x", function(x) NULL, formal=T),0,2)

which would give me... 4.

Thank you,
Tristan
