How i can use a graphically switch in order to change the value of variable in R?

[MeMarcoMe]

HI!
My name is Marco, i have a little problem with R. I need to make an add on for an existing program. For this i need to change a variable and look what this change do in a real time graph. I will give to you an example.

EXAMPLE IMAGE

I have a function y=m*x^g+q, i have some variable fixed, and other variable that the user can put or change manually, and i have the variable g that i need to monitorate while it change. When, with the mouse, the user switch the number of G the graph must change in live wiev.

Can you tell me how i can do that with R? Even if i can do it with other languages but even for R.

Thank you so much!
