[R] equation on the object

[Ronaldo Reis Jr.]

Hi,

I try to put an equation on a object to use in curve for example,
but it don't work, it possible to make a object of an equation?

ex.

fx <- a + b*x
for(a in 0){for(b in 1){curve(fx,...)}}

Thanks you
Ronaldo

ps. Exist in R any functions to estimate severals curves parameters (non 
interactive) for a dataset? Something like table-curve 2d.
