[Rd] "S4"-style methods and classes in R
Mon, 11 Dec 2000 09:20:47 -0500 (EST)
A preliminary version of an R package for classes and methods is
available from the omegahat web site:
Documentation and source for download are available from this page.
The goal is to support an API that would provide compatible facilities
for defining classes and methods in R and S-Plus. For the moment, the
"API" is roughly taken from "Programming with Data", particularly
A revised version of that section is available, from the web page
above, modified a bit for R use.
This is a preliminary version; comments and suggestions on any aspect
would be much appreciated, before going more "public" with it.
The current version is all written in the S language, for
flexibility. Key portions (method dispatch at the least) will be
implemented in C later on for efficiency.
