Dear all! I'd like to do multiple imputation of missing values with s-plus libraries that are provided by Shafer (http://www.stat.psu.edu/~jls/misoftwa.html). I wonder, whether these libraries are compatible or somehow convertible to R (because I don't have S-plus), so that I can use this functions using the R Program. I would be happy if you could tell me, -if it is possible to use S-plus libraries with R -if yes, how I can use the S-Plus libraries in R Thank you very much, Will --
Are you looking for the packages `norm', `cat' and `mix' on CRAN?

Will, Here is a general answer.

These have all been converted to R libraries, by various people. Go to http://www.r-project.org and then, via "CRAN", to any convenient CRAN site, e.g. http://cran.at.r-project.org/ and then go to "Packages", which will take you to http://cran.at.r-project.org/src/contrib/PACKAGES.html where you will find a list of all extra libraries. In this list you will find "cat", "norm", "mix" and "pan", and each of these will take you to a page for the package in question from which you can download either the R source of the package or a compiled binary version for Windows or Mac OX-X, as well as the reference manual for the package in PDF format which summarises usage and provides examples of usage with supplied example datasets. As a general rule, the packages should work exactly as Schafer intended; any modifications introduced in the R versions are there either to avoid problems due to differences between R and S-plus, or to evade bugs or problems which may have been detected in Schafer's original software. These packages have been created directly from the S-plus code on Schafer's website. They have counterparts in the S-plus library "missing", whose routines are based on Schafer's originals. For "cat", "norm" and "mix" the corresponding S-plus routines are in the "Loglin", "Gauss" and "Cgm" [conditional gaussian model] families of routines in the S-plus "missing" library. I'm not sure about what corresponds to "pan". Nor am I sure what differences from Schafer's original public-domain software may have been introduced when the S-plus library was created.
