ChangeLog
2010-08-11 Martin Maechler <maechler@stat.math.ethz.ch>
* man/qbsks.Rd: make 'R CMD check' happy (again)
2009-12-10 Martin Maechler <maechler@stat.math.ethz.ch>
* DESCRIPTION (Version): 1.2-1, CRAN-released
2009-12-10 Pin Ng <pin.ng@nau.edu>
* R/looDesign.R (loo.design2): weights w[.] must be used in 'Xeq'
* R/l1Design.R (l1.design2): ditto
2009-02-24 Martin Maechler <maechler@stat.math.ethz.ch>
* DESCRIPTION (Version,Date): 1.2-0, CRAN-released 2009-02-25
* tests/multi-constr.R: add test example which failed in earlier versions.
* R/scobs.R (cobs): 'ic' is only used and hence returned,
when lambda == 0.
2009-02-24 Pin Ng <pin.ng@nau.edu>
* R/scobs.R (cobs): Change default ic from "SIC" to "AIC": Since
"SIC" performs better in quantile smoothing spline while "AIC"
usually is better for knots selection in quantile regression spline.
New optional 'nk.start = 2' argument, allowing to start with more than 2.
* R/drqssbc.R (drqssbc2): sort y-values of ptConstr;
- fix n0: "2*n.gradient";
- stop() when some coef[]s are NA.
* R/qbsks.R (qbsks2): add 'nk.start' argument
2009-02-18 Martin Maechler <maechler@stat.math.ethz.ch>
(Depends): 2.5.1 so we can better work with package startup messages.
* tests/*.R: trying to suppressPackageStartupMessages(..) was a
"fiasco"; (messages from SparseM, quantreg) ==> not done
* TODO: updated
2009-02-14 Martin Maechler <maechler@stat.math.ethz.ch>
* R/scobs.R (plot.cobs): new arg. ylim with better default for
cases where curve is *outside* data, e.g., when algorithm failed.
* man/cobs.Rd: a bit more about 'ifl'.

2008-01-24 Martin Maechler <maechler@stat.math.ethz.ch>

2007-05-02 Martin Maechler <maechler@stat.math.ethz.ch>

2007-04-30 Martin Maechler <maechler@stat.math.ethz.ch>
* DESCRIPTION (Version): 1.1-4 - not released

returns result "along x", and not along sort(x).
(".First.lib"): use packageStartupMessage in R >= 2.5.0
2007-04-27 Martin Maechler <maechler@stat.math.ethz.ch>

2006-08-07 Martin Maechler <maechler@stat.math.ethz.ch>
* DESCRIPTION (Version): 1.1-3.3
* R/drqssbc.R (summSparse): utility for nicer 'trace'ing of sparse
matrices.
* R/scobs.R (.print.part): utility function used in print.cobs()
and summary.cobs() for the 'coef'
* R/scobs.R (coef.cobs): accessor method
* tests/*.R and *.Rout.save: adaption to latest summary/trace features
2006-08-05 Martin Maechler <maechler@stat.math.ethz.ch>
* R/scobs.R (cobs): changed defaults for lambda.lo and lambda.hi
to be scale-equivariant also with respect to x. Then dropped '* sd(y)'
which was *wrong*.
(print.cobs): make sure that `ifl != 1' is "marked" in print, too.
2006-08-04 Martin Maechler <maechler@stat.math.ethz.ch>
* R/scobs.R (cobs): make 'lambdaSet' an argument with default as previously
* man/cobs.Rd: dito; added several plot[.cobs]() examples
2006-08-02 Martin Maechler <maechler@stat.math.ethz.ch>
* DESCRIPTION (Version): 1.1-3.2
* R/drqssbc.R (drqssbc2): tol.0res.y: not mean(y) but "scale(y)"
in order to aim for scale invariance.
Make default = 1e-8 * sc.y, since I found that quantreg's
sq.fit.sfn*() routines have their 'small' in "y scale".
* R/scobs.R (plot.cobs): many more improvements; latest is
'which' argument.
2006-08-01 Martin Maechler <maechler@stat.math.ethz.ch>
* R/scobs.R (cobs): new argument 'keep.x.ps = TRUE' (for returning
pseudo X 'x.ps').
* R/drqssbc.R (drqssbc2): return pseudo.x only when 'give.pseudo.x = TRUE'
as per default, and do return the *sparse* version.
2006-07-31 Martin Maechler <maechler@stat.math.ethz.ch>
* R/l1Design.R (l1.design2): if (nk <= 4) cannot build some constraints;
now allows some more "multi-constraints":
* tests/multi-constr.R: tested here
2006-07-29 Martin Maechler <maechler@stat.math.ethz.ch>
* DESCRIPTION (Version): 1.1-3.1
* tests/ex1.R, roof.R, wood.R: adapt to NON-compatible change of
using 'pp.sic' instead of 'sic' (!)
* R/scobs.R (mk.pt.constr): use small helper function
* R/scobs.R (plot.cobs): small improvements
* R/scobs.R (cobs): moved arg. 'w' up to just after 'constraint';
ideally should even come after (x,y) ...;
add 'keep.data' argument and return more - even if(!keep.data)
2006-07-28 Pin Ng <pin.ng@nau.edu>
* R/scobs.R (cobs): new default values for lambda.lo and lambda.hi;
slight changes in returned components: renamed 'sic' to 'pp.sic';
pp.ifl, icyc,..
* R/scobs.R (plot.cobs): new plot method for "cobs" objects
* R/drqssbc.R (drqssbc2): add 'small = 1e-8' to the
rq.fit.sfn[c]() calls. MM: --> becomes new function argument 'rq.tol'.
Better scaling of tol.0res for "eff.k" tolerance.
Tweaked definitions of ifl.idx, sic., k, icyc
2006-07-25 Martin Maechler <maechler@stat.math.ethz.ch>
* R/l1looDesign.R: split this file into the two files
* R/l1Design.R (l1.design2): since these are almost "parallel"
* R/looDesign.R (loo.design2): it's easier to compare them.
TODO: modularize !
2006-07-24 Martin Maechler <maechler@stat.math.ethz.ch>
* R/drqssbc.R (drqssbc2): more cleanup of unused arguments; start
making more use of 'trace'.
* R/scobs.R (cobs, getdim2): allow multiple 'constraints'
2006-07-19 Martin Maechler <maechler@stat.math.ethz.ch>
* R/drqssbc.R: get rid of 'nj0' argument (nj0 := length(Tlambda)
2006-07-18 Martin Maechler <maechler@stat.math.ethz.ch>
* R/drqssbc.R (drqssbc2): drop unused 'eps' argument; use new
argument 'tol.0res' for testing |res| "=" 0 - on a *relative* scale.
* R/scobs.R (cobs): do not shift the outer knots before calling
qbsks2(), since that does shift anyway. Do shift *as there*,
i.e., by a *relative*, rather than absolute amount.
2006-07-16 Pin Ng <pin.ng@nau.edu>
* R/scobs.R (cobs): Change default 'ic' from "aic" to "sic"; new
argument 'repeat.delete.add = FALSE', passed to
* R/qbsks.R (qbsks2): new arg. 'repeat.delete.add'; and loop to do
repeated knot additions and deletions.
* R/drqssbc.R (drqssbc2): fix typo 'msgT'; better warning msg for flag '4'
2006-07-15 Martin Maechler <maechler@stat.math.ethz.ch>
* many changes to rename the package and main function
from "scobs" to "cobs" and similar for the qbsks2() and
drqssbc2() functions.
2006-07-07 Martin Maechler <maechler@stat.math.ethz.ch>
* R/scobs.R (scobs): explicit (instead of "hidden") default
nknots = if(lambda == 0) 6 else 20; no warning any more
when user choses nknots (or 'knots') differently.
2006-06-19 Martin Maechler <maechler@stat.math.ethz.ch>
* R/scobs.R (scobs): added the 4 arguments from old cobs(),
* man/scobs.Rd: such that old cobs() calls should still work.
2006-06-17 Martin Maechler <maechler@stat.math.ethz.ch>
* README: merged 'ReadMe' and removed that: Cannot have a file
with the same lowercase(name).
