R help - Jul 2010 - [R-pkgs] heplots 0.9-3 and candisc 0.5-18 released to CRAN

I've just released the latest R-Forge versions of heplots 0.9-3 and 
candisc 0.5-18 to CRAN.
They should appear there within a day or two.

== heplots
The heplots package provides functions for visualizing hypothesis tests
in multivariate linear models (MANOVA, multivariate multiple regression, 
MANCOVA, etc.). They
represent sums-of-squares-and-products matrices for linear hypotheses 
and for
error using ellipses (in two dimensions), ellipsoids (in three dimensions),
or by line segments in one dimension.  Both of these require the latest 
version of car (2.0-0)
but allow some backward compatibility with car 1.x-x

The most substantial change is that (with car 2), heplots now handles 
repeated measures designs
and doubly multivariate designs within the multivariate linear model 
approach.  A vignette
on this has been written, but is not yet included in the package.
New since the last CRAN version:
 Version 0.9-3 (2010-07-27)
 o Added gsorth() for Gram-Schmidt orthogonalization of a matrix or data 
frame, preserving
    column means and standard deviations
 o Avoid Deprecated warnings (linear.hypothesis) with car2
 o Fixed documentation warnings with car2 (linear.hypothesis, data.ellipse)
 
 Version 0.9-2 (2010-02-12)
 o Added demo/Big5.R
 o fixed buglet with text3d causing rgl to crash (thx: Duncan Murdoch)
 o switched inst/CHANGES to NEWS
 o Added data/RatWeight and examples
 o Added data/Headache and examples
 o Fixed buglets in heplot, heplot1d, heplot3d regarding number of variables
 o Added etasq.mlm methods for multivariate measures of association (\eta^2)
 o Return ellipse radius from heplot, heplot3d

Version 0.9-1 (2010-01-1)
 o heplot.mlm, pairs.mlm, heplot3d.mlm now work for repeated measure designs
   with only covariates on the rhs.
 o Implemented heplot1d() for repeated measures designs (untested)
 o Revised documentation for repeated measures
 o Added center.cex to heplot.mlm()
 o Revised mark.H0() to handle 3D plots also
 o Added Adoption data -- MMreg with repeated measures
 o Added ReactTime data -- 2 within-S, no between-S factors
 o Fixed bug with icontrasts
 o Added markH0 argument to heplot
 o Added label argument to mark.H0()
 o Added arrow3d()
 o Fixed buglet in pairs.mlm (type)
 
Version 0.9-0 (2009-12-25)
 o Implemented 2D HE plots in heplot.mlm for repeated measures designs 
by adding
   idata=, idesign=, icontrasts= arguments. 
 o imatrix= argument  for doubly-multivariate designs implemented, but 
depends on car 2.0+
 o Updated example(OBK)
 o Updated example(WeightLoss)
 o Implemented 3D HE plots in heplot3d.mlm for repeated measures designs 
(OK)
 o Implemented pairs() for repeated measures designs (OK)

== candisc
candisc includes functions for computing and visualizing generalized 
canonical
discriminant analyses for a multivariate linear model. They are designed 
to provide low-rank visualizations of
terms in a \code{mlm} via the \code{plot} method and the \pkg{heplots} 
package.

Recent changes:
Version 0.5-17 (2010-2-11)
o  Allow to select canonical dimension in plot(candisc(), which=)

Version 0.5-18 (2010-7-27)
o  Fixed predictor.names problem with car_2.0-0
