Canoco 4.5 for Windows is now shipping! A full Windows version of the older DOS programCANOCO 3.1

A FORTRAN program for canonical community ordination by [partial] [detrended] [canonical] correspondence analysis, principal components analysis, and redundancy analysis.
Canoco 4.5
by Cajo J.F. ter Braak of the Plant Research Institute (PRI), at Wageningen, The Netherlands.

CanoDraw for Windows now included with Canoco 4.5

A companion program to CANOCO. CanoDraw produces on-screen graphs and publication quality output suitable for use in Mac and PC image editing and desktop publishing software, as well as direct output to various hardcopy devices.

Cornell Ecology Programs (CEP)

A set of indirect ordination and classification programs developed under the aegis of the late Dr. Robert H. Whittaker and written by Mark O. Hill (DECORANA, TWINSPAN), Hugh G. Gauch, Jr. (ORDIFLEX, COMPCLUS) and others. The major programs are available in an MS-DOS version implemented by Charles L. Mohler.

Y2K: Lack of Problems with Year 2000

None of our software performs any date operations. Therefore the operation of all of our programs is unaffected by the transition to the year 2000 or leap year calculations.
