[R] parameters' value

[Duan Zhigang]

Hi, I am a new user of R. I am trying to use R to do some nonlinear modeling. However, I can not find how to get the parameters's value back.

Here is the code in S-plus: 

ycos1.nl <- nls(y ~ m +ac*cos(2*pi*f*t) +as*sin(2*pi*f*t), start=nl.st, trace=T)

## store model info after satisfactory model has been found
cNL1 <- c(ycos1.nl$parameters[1:3],0)

What is same code in R? 

Thanks a lot.
