R, suppress plot from curve function

Question

when using the "curve" function in R, how do you suppress/stop the plot from showing up? For example, this code always plots the curve

my_curve = curve(x)

Is there a parameter to do this or should I being using a different function? I just want the xy points as a dataframe from the curve.

Answer 1

curve() is from the graphics library and is unhandy for generating lists.

Just try using:

x = seq(from, to, length.out = n)
y = function(x)

If you stick to the curve function, the closest to a solution I know is adding dev.off() after the curve() statement!

Answer 2

Here's a way to take advantage of the part of curve that you want without generating a plot.

I made a copy of the curve function (just type curve in the console); called it by a new name ( curve2 ); and commented out the four lines at the end starting with if (isTRUE(add)) . When it's called and assigned, I had a list with two vectors— x and y . No plot.
