NEWS
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.
