Authors/Contributors and Citation
Fields has drawn heavily from its predecessor, FUNFITS, to the

Fields Development Team is:
Doug Nychka, Reinhard Furrer,
Steve Sain, Barbara Bailey, Stephen Ellner, Perry Haaland, Michael
O'Connell, Sarah Hardy, Jungmin Baik, Wendy Meiring, J. Andrew
Royle, Montserrat Fuentes, Tim Hoar,
Claudia Tebaldi, and Eric Gilleland.
The R version of Fields is currently available for UNIX, Linux and Windows through the Comprehensive R Archive Network (CRAN). [See the contributed packages section]. The Windows version is available as a binary, the others can be readily built in UNIX/LINUX. Currently, due to time constraints, we no longer offer fields for Splus.
