I obtain the coefficients of a nonlinear function thus. ------------------------------------------ m=nls(y ~ a + b*x + c*x^2 + d*x^3 + e*exp(x)+f*log(x)+g*log2(x), start = list(a = 0, b = 1, c = 1, d=1, e=1, f=1, g=1))
c=coef(m) ------------------------------------------- However, when I look at c[1], I get something like a 2.345678 How can I extract 2.345678 as a number? Thanks very much in advance, Peter. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
