Note: Although the software announced here was written to work
with R, we have done some testing under S-PLUS and believe it to
be compatible with S-PLUS as well. We know of no reason it should
NOT be compatible. We use "S" below to include both dialects.
We announce the availability of three related software libraries:
C2R, ADMB2R, and For2R (together, X2R). Each contains output
routines to simplify transfer of complicated data structures from
models written in a compiled language to S. The user's data can
be written as a structured ASCII file which, when read by S with
a single dget() function call, will become an S data object of
type list. The list, of course, may contain components such as
data frames, matrices, and other lists.
These are NOT libraries of S functions; rather they are subroutine
libraries to be used with programmers' own modeling codes.
Languages supported are Fortran 95 (with For2R), C and C++ (with
C2R) and AD Model Builder (with ADMB2R). Source code and users'
manuals are supplied.
This work has been tested and used by the authors. However, any
software may contain bugs, and these works are classified by NOAA
as "Experimental Products." Although the software is supplied
with no warranty whatsoever, bug reports, suggestions, and
extensions are solicited (send to Prager or Martin). The authors
will attempt to fix all bugs promptly and to add requested
features.
Software is now available at CRAN, http://cran.r-project.org/ ,
and is expected to propagate to mirrors shortly. Look under
"Software / Other" for the current X2R distribution.
