VERSION 0.1-3 o as.lm and as.lm.nls can be used to convert an "nls" object to an "lm" object which is tangent to the nls object. Untested. o as.lm.nls uses proto package hence new dependency o added algorithm = "random" which samples maxiter rows from start if start is a data frame with more than 2 rows whereas if start is a data frame with exactly 2 rows it will take maxiter random points from the rectangle whose boundary is defined by the rows. o if nls exits with an error nls2 uses NA as the return value of that nls call instead of stopping with an error VERSION 0.1-2 o fixed problem with update not working with objects produced by nls2. o fixed number of iterations and tolerance displayed when using algorithm = "brute-force". o if there are exactly two rows in start= then a grid of starting values is formed so that there are at least maxiter points on the grid. o start can be an nls object in which case coef(nls) is used. VERSION 0.1-1 o documentation and DESCRIPTION file tweaks. VERSION 0.1-0 o initial release.
