	algorithm'.  Applies e.g. also to the nlme-stall.R example.

2018-02-27  Brian Ripley

	* DESCRIPTION: Update Date. (Still unreleased.)

	platform-dependent tolerances.

2018-02-26  Brian Ripley

	* src/init.c, src/rs.f: The 2018-01-31 change is broken (passes
	pointers as doubles).  Try a simpler approach, to replace PYTHAG
	in rs.f by a wrapped call to the C99 function hypot().

2018-02-16  Brian Ripley

	* DESCRIPTION (Version): 3.1-131.1, for R 3.4.4.

	MEestimate.

	* R/newMethods.R: Revised assignments in plotting methods to be
	compatible with the Murrell/Sarkar preliminary trellis package.

2000-12-08  Douglas Bates  <bates@stat.wisc.edu>

	* R/lme.R: Changed all calls to dist in lme.R, gls.R and
	corStruct.R to use the argument "method" rather than "metric".

	* R/pdMat.R: Replaced calls to .Fortran("dbksl", ...) with calls
	to the R function solve() for R-1.2.0 where the S_compat.c file
	has been removed.

	* inst/scripts/ch01.R: Added the chapter scripts from
	"Mixed-Effects Models in S and S-PLUS" to the inst directory.

	* man/formula.nlme.Rd: Modified the examples in this and many
	other .Rd files to use the Loblolly data and the SSasymp
	self-starting function.	 There were many occasions where the
	Soybean data was being fit to a default formulation of an nlme
	model just to get things like a formula.  This fit of the Soybean
	data is difficult and time consuming and not very illuminating.

2000-11-30  Douglas Bates  <bates@stat.wisc.edu>

	* src/matrix.c: Removed dependency on S_compat.h by replacing
	calls to dqrdca with the equivalent call to dqrdc2.

2000-07-24  Saikat DebRoy

	* Changed various uses of do.call to eval.  The reason for doing
	this is to allow calls to the function calling eval from within
	another function.  It's the old scoping problem again.

	* src/nlme.c, src/nlmefit.c: Added mixed_grad in calls to optif9.

	reStruct objects.

	* src/pdMat.c (logChol_pd): new function.

	* R/pdMat.R: Added back the pdLogChol class and associated
	methods.


2000-07-03  Douglas Bates  <bates@stat.wisc.edu>

	* man/corFactor.corStruct.Rd: Added an alias for
	corFactor.corNatural

	* src/nlmefit.c (internal_loglik): Changed the return value on
	error from R_NegInf to -DOUBLE_XMAX so the optif[09] optimizers
	will work properly.

	* src/corStruct.c (corStruct_factList): Provided a correct call to
	the R version of F77_CALL(chol) here and everywhere else in this
	source file.

	* R/zzz.R: Removed the deprecated call to provide

2000-03-17  Douglas Bates  <bates@stat.wisc.edu>

	* added many data sets

	* incorporated patches from Brian Ripley to use optim for the
	optimization rather than nlm

	* src/nlmefit.c (internal_loglik): Returned R_NegInf instead of
	generating a error on a singular precision matrix.

	* DESCRIPTION (Depends): Changed Depends to R version 1.0.1
	because of problem with assigning components of lists.

1999-12-23  Douglas Bates  <bates@stat.wisc.edu>

	* TITLE: Changed the title to nlme
