This zip file contains R code (it also works in Splus) and help files for applying the False Discovery Rate (FDR) methodology to determining significance using multiple p-values. A text file with just the code is also available. To use the code, source the file ('source fdr.R') and then use the function called 'fdr'.
For a Matlab version, download this .m file. This code also works in octave, an open source version of the Matlab language, but you need all 5 functions in their own individual .m files, so after downloading the file, manually create individual function files from the fdr.m file.
Additional details are available in our technical report, in press in Journal of Climate. Last updated: May 27, 2004
