Version 2.0-14 2005-02-07 Improve messages, support translations
Version 2.0-13 2004-11-11 Update sm.density.compare to pre-2.1 after
bug report from Deepayan Sarkar.
Scripts trwlgam[13] now work.
Use "console" pager on Windows.
Version 2.0-12 2004-09-04 sphimage used a[ind] <- b[ind] with NAs in ind.
Added NAMESPACE.
No longer use .sm.home, but system.file.
Use package gam in scripts:
trwlgam2 mackgam smackgam now work.
Version 2.0-11 2004-08-04 One .Rd error, data -> smdata, remake INDEX
Version 2.0-10 2004-07-29 Remove references to packages modreg and sm.
Make provide_data more careful about where
(as 'trees' duplicates a base dataset).
Version 2.0-9 2003-12-18 Set seed for running scripts.
Version 2.0-8 2003-09-12 Avoid 'nlevels' as var name.
Version 2.0-7 2003-07-18 Documentation improvements.
Version 2.0-6 2003-06-03 Avoid generating lty=NA, use PACKAGE=.
2.0-5 was unreleased.
Version 2.0-4 2001/10/10 tree.q did not work in R, minor improvements
to documentation.
Version 2.0-3 2001/08/08 QA changes, e.g. T -> TRUE in scripts.
Version 2.0-2 2001/06/12 Many help-file improvements.
Version 2.0-1 2000/12/08 Version 2 of sm, sm.rm(optimize=TRUE) works.
Version 1.0-3 1999/08/15 Moved .sm.home to package:sm, made ts examples work.
Version 1.0-2 1999/04/02 Modified for 0.64, using R's chull, jitter,
inst/* mechanism, data/00Index, file.* functions.
Version 1.0-1 1999/02/20:
I renamed plot.density (which causes a name clash, and is not a plot method)
to smplot.density.
All the example scripts work except those depending on gam:
trwlgam1 trwlgam2 mackgam trwlgam3 smackgam
(and the gam in mgcv does not work with these).
R discrepancies:
===============
is.matrix is false for data frames: I used isMatrix in zzz.R instead.
Colours are (mainly) named in the R version.
In polygon() border gives the colour, not a logical for plotting.
points() does not use the current cex and pch in R.
Labels formed by deparse(substitute(x)) need to evaluated before x is altered.
persp() has fewer arguments, and the default viewpoint did not seem a
good choice for these plots, so I altered it.
glm.fit() has different arguments, and the X matrix must have column names.
Further, weight-0 points do not get the linear predictor set.
is.na(x) fails in R if x is NULL.
Some functions used `break' where `return()' was meant: this does not
work in R.
The uses of unix() and assign() needed revising.
detach() named objects seemed to fail, so I used pos= instead.
