	* tests/rq.R (stopifnot): regression tests added.

	* man/plot.Rd: improve; notably plot.qss2() arguments

	* man/predict.rqss.Rd: no rm(.) in example; improve

2006-08-12  Martin Maechler  <maechler@stat.math.ethz.ch>

	* R/quantreg.R (akj): 'iker2' is never used; add a check for
		length(p) == length(x) [vignette did not fulfill this and
		gave spuriously wrong results because of initialize memory
		in .Fortran("arj" ...) !
	* inst/doc/rq.Rnw: fix the akj() weights
	* man/akj.Rd: no 'iker2'; cleanup

2006-08-11  Martin Maechler  <maechler@stat.math.ethz.ch>

	* tests/run-demos.R: one simple test suite ..

	* demo/cobar.R: make sure this also works when 'rgl' does not
	* demo/Frank.R: clean up a bit
	* demo/engel1.R: nicer; + legend
	* demo/engel2.R: is incomplete => if(FALSE) { .. } for the moment
	         FIXME: use vignette !

	* man/engel.Rd: added somewhat interesting example.

	* src/chlfct.c (chlfct): eliminate goto; correct timing also when
	error; more comments (timewd, etc)

	* R/sfn.R (rq.fit.sfn, rq.fit.sfnc): only keep what's needed from
	.Fortran(). Save one (sparse) matrix multiplication

	* src/srqfn.c:    new from src/srqfn.f ...
	* src/srqfnc.c:   new from src/srqfnc.f ...

2006-08-05  Martin Maechler  <maechler@stat.math.ethz.ch>

	* src/cholesky.c: new from src/cholesky.f which must be renamed
