We announce the availability of the Fortran 95 module "For2R", which
makes it easy to write complicated R data structures (i.e., lists of
lists, matrices, dataframes, ...) from Fortran programs. By a series of
subroutine calls, program outputs can be written to a file readable by R
with a single "dget" function call. This facilitates automated
graphics
generation and other postprocessing of model results.
A downloadable ZIP file of For2R is available from
http://shrimp.ccfhrb.noaa.gov/~mprager/Rinter.html and includes Fortran
source, documentation, and an example.
We are working on similar code to interface C++ with R. An extremely
crude version of such code is available from the same page. Though the
C++ code will be totally replaced, the download includes sample output
and R graphics functions for automated processing of a fisheries example.
Although For2R is much nicer than our current C++ code, it should all be
considered beta-test code, and it is supplied with no warranty
whatsoever. Bug reports and suggestions are welcome.
