Notes on "scobs" as received from Pin Ng
----------------------------------------
7) The new (2006-07-28) behavior:
> cobs(x,y, "decrease", knots = ux, nknots = length(ux))
Warning message:
The number of knots can't be equal to the number of unique x for degree=2.
'cobs' has automatically deleted the middle knot. in: cobs(x, y,
"decrease", knots = ux, nknots = length(ux))
seems wrong to me: Smoothing.splines are degree =2 and have
knots == unique(x). It really depends on the boundary conditions (or
knot multiplicity at x[1] or x[length(x)].
6) weights 'w' are *NOT* used in l1.design2() and loo.design2()
---- ==>
1) non constant-weights should give a warning for the moment
2) FIXME !!!
--------------------------------------------------------------------
OLD
----
0) added ./Rbuildignore (as for 'cobs' package)
1)
src/Makevars uses
libs/cholesky.a which is completely inappropriate! The pkg MUST
contain source code only!
--> fixed src/Makevars; removed libs/
1b) ./ReadMe removed and merged to ./README
2) tests/ was completely missing in 'scobs' --> take the one from 'cobs'
3) data/ contained much less data sets than ~/R/Pkgs/cobs99/data/
--> filled up
4) src/New/ and src/Orig/ also removed
5) rm CONTENTS INDEX .R-porting
