Here you can find some of my contributions to R.
For a long time it has been limited it to the modttest package, but after some time I have decided to add other pieces:
modttest implements Dutilleul's sample size correction for the assessment of the correlation between spatial processes. The merit is not mine, since it relies heavily on the original fortran program by Pierre Legendre, but some people have already found it quite useful. If you also do, please, let me know. I modified it slightly so it can handle more than two variables at the same time, great circle distances, and a few other upgrades.
GDBLDA allows performing a Generalized Distance Based Linear Discriminant Analysis. Although a pre-existing S code from J. Robinson was available, I was so focused at that moment that I did not read the footnote in the paper by Anderson and Robinson, and implemented the method from scratch. Originally intended to circumvent the criticisms during the review of this paper, we never used it. I hope that it is useful to someone else in the future.
syrjala encapsulates a fast and flexible implementation of the original method by Stephen Syrjala for the comparison of the spatial distribution of two spatial processes in co-located samples. It has been included in the R-package ecespa.
