[R] Regression on non linear model

[Peppy]

Dear Help desk,

I have a model that I believe to be non linear.  The relationship is
something like:

Response = Var1 + Var1^2 + Var1^3

Can I examine this relationship using glm or lm?  However, glm or lm gives
out pnly 1 coeficient for the model which is on Var1,  unless I created some
dummy var like (Var2 = Var1^2 and Var3 = Var1^3).

Is there any other function handling this relationship?  

My R is 0.64.2

Thank you,
Peppy
