parameters' value

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?
The preferred approach is to use the coef extractor function. This works in both R and S-PLUS. coef(ycos1.nl)
