R packages - Jan 2011 - New package versions for distr- and robast- families

------------------------------------------------------------------------
------------------------------------------------------------------------

New versions 2.3 of our distr-family of packages are now
available on CRAN.

(i.e.; startupmsg, SweaveListingUtils,
       distr, distrEx, distrDoc, distrEllipse,
       distrMod, distrSim, distrTEst, distrTeach)

Most importantly, we have included:

+ a quasi-MC trick by Nataliya Horbenko to better produce
  image distributions under complicated, not necessarily
  monotone transformations
+ enhanced function qqplot
+ (enhanced) support for GEV distribution
+ new functional kMad
+ as well as several bug fixes

For more details see the corresponding NEWS files
(e.g. news(package = "distr")
or using function NEWS from package startupmsg
i.e. NEWS("distr")).

We are looking forward to getting your RFEs, bug reports 
or simple feedback,

Best,

Peter, Matthias, Nataliya

------------------------------------------------------------------------

New versions 0.8 of our RobASt-family of packages are now
available on CRAN.

(i.e.; RandVar, RobAStBase, ROptEst,
       RobLox, ROptEstOld, ROptEstTS, RobRex,
       RobLoxBioC)

Most importantly, we have included:

+ a quasi-MC trick by Nataliya Horbenko to better produce
  random variables under complicated not necessarily
  monotone transformations

+ enhanced functions
   infoPlot, (plots relative information used for coordinates
              of a parameter estimator)
   ddPlot, (distance-distance plot)
   cniperPointPlot, (cniper concept for seemingly harmless
            contamination behavior)
   qqplot (now gets outlier corrected versions)

+ new risks: asAnscombe, asL1, asL4
  for asymptotic L1 L4 risk, and optimal bias robust estimator,
   to given efficiency loss in ideal model

+ new helper methods makeIC
  to apply to functions or list of functions
  for easily producing (suboptimal) ICs

+ new function getReq for two ICs IC1 and IC2
  to compute a radius interval where IC1 is better
  than IC2 acc. to G-Risk

+ new function getMaxIneff() to compute,
  for any IC of class 'IC', the maximal inefficiency
  for radius r varying in [0,Inf)

+ as well as several bug fixes

For more details see the corresponding NEWS files
(e.g. news(package = "RobAStBase")
or using function NEWS from package startupmsg
i.e. NEWS("RobAStBase")).

We are looking forward to getting your RFEs, bug reports 
or simple feedback,


Best,

Peter, Matthias, Nataliya
