New versions released for the distr family of package
-------------------------------------------------------------------------------
We would like to announce the availability on CRAN (with possibly a
minor delay until on every mirror) of new versions of our packages
in the "distr"-family (version 2.1), i.e.; "distr", "distrEx",
"distrSim", "distrTEst", "distrDoc", "distrMod", and "distrTeach",
as well as our supporting package "startupmsg" and the new
(supporting) package "SweaveListingUtils".
[all of them require R >= 2.6.0]
For details, please also refer to the NEWS file of the corresponding
package, accessible via NEWS("<pkgname>") [after require(<pkgname>)]
-------------------------------------------------------------------------------
Devel versions on r-forge
-------------------------------------------------------------------------------
Development of these packages is done under r-forge project /distr/:
http://r-forge.r-project.org/projects/distr/
http://distr.r-forge.r-project.org/
If you find this project interesting and would like to collaborate, you are
warmly welcome. You may find more information on how to collaborate under
http://distr.r-forge.r-project.org/HOWTO-collaborate.txt
We look forward to receiving questions, comments and suggestions

Below you find a list of major improvements in version 2.1:
%---------------------------------------------
SweaveListingUtils:
%---------------------------------------------
+ a new package devoted to joining markup provided by TeX package
'listings' with Sweave;
+ also covers inclusion of code sniplets from an url
(notably r-forge) in order to ease consistency
of documentation with code that is being developed.
see also ?lstinputSourceFromRForge and
vignette "ExampleSweaveListingUtils"
%---------------------------------------------
distr
%---------------------------------------------
COMPOUND DISTRIBUTIONS
+ new support of compound distributions,
see ?CompoundDistribution, class?CompoundDistribution
ENHANCED ACCURACY
+ by log scale
Following Peter Dalgaard's hint
https://stat.ethz.ch/pipermail/r-help/2008-September/174295.html
we use the log.p argument to be able to simulate accurately from
the far out tails.
+ refined collapsing technique for DiscreteDistribution
+ more frequent use of FFT for convolution by better treatment of
joint lattices
AUTOMATIC GENERATION OF IMAGE DISTRIBUTION
+ slot r is now /much/ faster / slimmer for results of *,/,^
+ slot d for results of *,/, exp() now is correct at 0 by extrapolation
COMFORT METHODS
+ getLow/getUp methods (for "reasonable" endpoints for distributions with
possibly unbounded support) for
*DiscreteDistribution,
*AbscontDistribution,
*UnivarLebDecDistribution,
*UnivarMixingDistribution
+ q.r, p.l (methods for right continuous quantile function
and left continuous cdf) for
* DiscreteDistribution
* AbscontDistribution (takes care of constancy regions in p)
* UnivarLebDecDistribution
* UnivarMixingDistribution
+ prob methods (returning vectors/matrices of probabilities of support)
+ DiscreteDistribution
+ UnivarLebDecDistribution (conditional/unconditional)
+ p.ac, d.ac, p.discrete, d.discrete methods (for
UnivarLebDecDistribution)
now conditional/unconditional
%---------------------------------------------
distrEx
%---------------------------------------------
FUNCTIONALS
+ expectation gains explicit arguments to set accuracy locally;
+ median and IQR are now defined for UnivariateCondDistribution
+ cross-checked (and bug-fixed) particular functionals against
general implementations
DISTRIBUTIONS
+ gains distribution Pareto; ported from pkg actuar by Nataliya Horbenko
DISTANCES:
+ introduces distances asymmetric total variation distances
*OAsymTotalVarDist
*AsymTotalVarDist
+ TotalVarDist and HellingerDist gain extra arguments
to better control the integration range and exactness
%---------------------------------------------
distrMod
%---------------------------------------------
MODELS
+ added mad.const to guarantee for mad-consistency in location scale model
for general central distribution
TRAFO
+ fixed some inconsistencies with slot trafo:
now when trafo is a function, we try to keep it as a function under
moves of the parametric model
+ trafo.fct() to access the "function" aspect of trafo
+ trafoEst() transforming an estimator of class "estimate"
consistently by a "trafo" function
ESTIMATION
+ enhanced Covariance calculation for CvMDist-MDE
+ modified output in show - Confint-class
%---------------------------------------------
PLOTTING
%---------------------------------------------
+ enhanced automatic plotting range selection for distributions
+ ylim can now be matrix-valued giving panel-individual values
+ selection of panels to be plot by argument to.draw.arg
+ L2ParamFamily plot in distrMod is now as flexible as plot-methods in
pkg distr
+ more flexible panel axis annotation
%---------------------------------------------
DOCUMENTATION:
%---------------------------------------------
+ updated large vignette "distr" in distrDoc
+ updated vignette "ExampleSweaveListingUtils" in pkg SweaveListingUtils
+ updated vignette "How to generate new distributions in packages distr,
distrEx" in pkg distr
+ new section "Extension packages" in package-help to package distr,
see ?distr
