I want to plot for a range of values in my function in R [closed]

Question

I have a function in R that has 3 arguments: a,b,c. The arguents b and c don't change but I want to evaluate the function for a range of values of a, meaning I want a to be 10-1000. I then want to take these values and plot them in R.

Any idea how I can do this?

Answer 1

If your function is already vectorized (i.e. will take a vector of a values) then

curve(myfunction(a = x, b = 3, c = 2), from = 10, to 1000)

would work. If not, you could do

vc <- Vectorize(myfunction)
curve(vc(a = x, b = 3, c = 2), from = 10, to 1000)

curve() also has an n argument that determines the numbers of points to evaluate in the range (the default is 101).
