I have just put R-0.62.2.tgz and R-0.62.1-0.62.2.diff.gz into the FTP
area at Auckland. As usual, do not fetch it from there unless
absolutely urgent, because of the NZ Internet billing system. The
files should get mirrored to the main CRAN site in Vienna tonight and
the rest of CRAN within days.
[This time I seem to have managed to get the release out on the same
date for all core team members -- the Auckland time stamps say "Jul 10
23:59"...]
This is a patch release, mainly fixing bugs, but we have also let some
new features slip in this time.
Here's the top of the CHANGES file:
CHANGES IN R VERSION 0.62.2
(The new functions predict.glm, poly, aov, alias, biplot.default and
biplot.princop, update.default and rug all come from Brian D. Ripley,
who is also responsible for finding and/or fixing a lot of the bugs)
NEW FEATURES
o predict.glm() added.
o text() is generic.
o update.default() (replaces update.glm() and update.lm()).
(This will only work if you comment out update.lm and
update.glm in the sources, or disable them with
update.lm<-function(object,...)NextMethod(), etc.)
o predict.lm() changed towards S-plus compatibility. Intervals are
still available via interval= argument.
o zapsmall() function.
o polygon() now handles NAs
o options(show.signif.stars = TRUE). If FALSE,
summary.lm and similar functions do *not* print significance stars
anymore.
o poly() for [g]lm modelling.
o aov() for Analysis Of Variance [anova].
o alias() for displaying ``aliased'' factor levels in (>=2)way
anova.
o mva: Now has biplot and biplot.princomp
o rug() plot.
o new src/library/profile/Common.R for OS-independent intialization.
o new date stamp mechanism (ensures that prerelease versions carry
correct date)
BUG FIXES
o abbreviate() now always retains the first letter.
o attr() partial matches for attribute name.
o axis() accepts graphical parameters.
o binomial() accepts factor responses.
o cbind() works with data frames.
o contrasts() gives simpler labels (like S) for factors with
two levels.
o contrasts<-() now has a how.many= argument.
o contour() and image() can accept a list to specify the matrix.
o contr.poly() uses orthogonal polynomials (like S) not raw
polynomials.
o data() could fail with a partial match to the dataset name.
o density() works correctly if from= or to= are used.
n= can now take any value, not just a large power of 2.
o expand.grid() now accepts more than two arguments,
or a list of factors.
o factor() and ordered() handle their levels argument better.
o family.glm() now returns the correct family (including link etc).
o legend() now knows about lwd.
o match.args() works correctly for default arguments.
o model.frame.lm() did not invoke `lm'.
o model.matrix() calls model.frame() if needed.
o model.response() now returns names, so glm() gives names to
residuals, fitted values, etc.
o quasi() works in glm() (was missing aic component).
o seq() sometimes omitted the final value due to rounding error.
o terms.formula() and update.formula() now resolve `.' in formulae
and tidy up `(a + b) - b' etc.
o ... is now passed down correctly to functions inside functions.
o save.image didn't work (Martyn Plummer)
o abs() instead of fabs() in seq.c crashed R on Digital Unix
o model.matrix() gagged on variables with complicated names
o saturated models acting up in glm
o various improvement of build procedures
o rbind(NULL, matrix) core dump
o density() default 'bw' now 0.9*(...) instead of 1.06*(...)
[=Silverman's rule of thumb].
o detach(2) now works.
o format() doesn't drop names anymore.
o format.pval() works with NAs.
o print.[summary.][g]lm() functions print numbers better formatted.
o legend() now also works properly in log coordinates.
o backsolve() now working; bakslv.c not depending on
Fortran_underscores.
o Tick marks acting up on log axes in postscript (fix from Martyn Plummer)
o The Rd format has a new section \details{} (needed for proper
Sd2Rd translation). \R was not understood for nroff
conversions, longer dashes (-- and --- in latex syntax) are
now converted properly.
o prompt.default() now carries "\details{}".
o R [ SHLIB | COMPILE ] were broken on some Solaris systems
due to use of bash syntax. R [ INSTALL | COMPILE | SHLIB ]
now use a MAKE environment variable if present.
R INSTALL only rebuilds man pages if they are not already
up to date.
