Hi all,

I want to provide the result from D() to curve(), because I want to plot the k-th derivative of some functions. Actually, I copy from console the result given by D() and paste inside curve(). With a lot of functions and high degree differentiation this process is tedious. Can I provide directly??

# what I actually have done (very simple function)
D(expression(x^3), "x") # copy this result
curve(3 * x^2) # paste inside

# my failed attempts
curve(as.expression(D(expression(x^3), "x")))
curve(as.character(as.expression(D(expression(x^3), "x"))))
curve(noquote(as.character(as.expression(D(expression(x^3), "x")))))

Thanks in advance.
