NEWS
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.
