nlmrt 2016.3.2 (2016-03-04)

• An example from Gabor Grothendieck with 0 sumsquares raised an error in summary.nlmrt() due to crossprod() returning a 1x1 matrix rather than a scalar. Fixed with the use of as.numeric().
• NAMESPACE exported summary, print and coef methods replaced with S3method() statements
• DESCRIPTION updated to current standards
• Minor tweak in vignette (encoding line)

nlmrt 2014-7.16

• These were, unfortunately, not recorded here

nlmrt 2013-8.26

• Relative offset convergence test (not exactly as in nls()) residual and jacobian in summary & print methods
• coef() method in nlmrt.R so names carried through
• summary() and print() cleanup
• partial and minor documentation improvement

nlmrt 2013-8.10 (2013-08-11)

• fix line length issue in examples

nlmrt 2013-7.9

• Added control list elements to .Rd files for nlxb and nlfb, with reference in wrapnls.
• Put in a test for very small sum of squares in nlfb and nlxb.

nlmrt 2013-3.16

• Result element coeffs changed to coefficients. This alters wrapnls.R code also.

nlmrt 2012-9.03

• More features in summary().
• summary() for output from different functions. Should display constraints if possible as per JNMWS codes. Warnings / Notes fixed re: dependencies in vignette, methods.
• Sort out display in vignette Note warning "unstated dependencies in vignette"

nlmrt 2012-8.12 (2012-08-13)

• Bounds and masks examples in nlmrt-vignette.

nlmrt 2012-8.04

• Vignette nlmrt-vignette updated.
• Functions to convert expression to residual, Jacobian, sum of squares and gradient functions (for use with optimx or nlmrt:nlfb or minpack.lm:nls.lm
• The examples in ./inst/examples/ are calling routines that have been renamed. These have, I believe, been fixed.
• nlfb() needs an explicit Jacobian function and needs a way to compute numerical Jacobian if omitted. Fixed, I believe.

nlmrt 2012-6.01

• Removed diagnostic printout of bdmsk in nlfb

nlmrt 2012-4.15

• Added nlfb to allow functions for residual and Jacobian. These are developed from the expression for the residuals as a model in nlxb.
• Bounds now in wrapnls.
• Note misleading trace output in nls() runs with bounds.
