VERSION 0.3-3 o fix bug that occurred when using "port" VERSION 0.3-2 o fix bug in 0.3-0 related not being able to access data= in some situations VERSION 0.3-0 o add lhs (Latin Hypercube Sampling) and plinear-lhs sampling algorithms o if all iterations fail return NULL o add README file o add INSTALL file o fix Example 5 in help file and change it to use plinear-lhs o fix number of iterations. Previously 1 iteration could display incorrectly. o fix weights. Do not ignore weights (includes contribution by Ben Bolker) o fix subset. Do not ignore subset argument. Note that if subset is specified then data must be specified as a data.frame. o add caveat to help file regarding start argument not supporting the nls grouped data list of vector format VERSION 0.2-1 o bug fix for case of only one parameter o start may now also be any object with a coef method VERSION 0.2-0 o algoirthm can be "plinear-brute" or "plinear-random" o corrected one nls2 example o trace is now used by nls2 to control printing. Previously it was only used to pass to nls. VERSION 0.1-5 o corce formula argument to a formula if its not already a formula VERSION 0.1-4 o NAMESPACE file added o as.lm removed 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.
