[R] Hmisc and Design Packages

[Frank E Harrell Jr]

New versions of the Hmisc and Design packages, including ones for Windows, may be found at http://hesweb1.med.virginia.edu/biostat/s/library/r

Thanks as always to Xiao Gang Fan <xiao.gang.fan1 at libertysurf.fr> for providing the Windows ports.

In Hmisc, new features for multiple imputation have been added to aregImpute and LaTeX and plot methods have been improved for summary.formula objects.  New functions spss.get and sasxport.get have been added to enhance how SPSS and SAS transport files are imported using the foreign package.  Variable labels, value labels, date, time and date/time variables are handled.  Various bugs have been fixed in Design, and a new fitting function glsD (Design's version of the nlme generalized least squares function gls) has been added as has the univarLR function.  glsD has an experimental cluster bootstrap option for nonparametric estimation of covariance matrices of regression coefficient estimates with repeated measures.  Details of changes along with installation instructions may be found at http://hesweb1.med.virginia.edu/s/Hmisc.html and .../Design.html.
