Dear R users

I have a question about how to fit data to a straight line. I tried nls to do it, but it didn't work.

The reason I want to fit data to a straight line is that I need to compare AIC or BIC values of the two models (a straight line model vs a nonlinear curve model). Fitting data to a nonlinear curve is straightforward, but I could not figure out how to fit the data to a straight line and therefore, I could not get the AIC/BIC values of this simple model. If I can get the AIC/BIC value of the straight line fit without actually doing a fit, that is also fine.

Thanks in advance.
