[R-sig-Geo] Cliff and Ord modified t-test for autocorrelated datasets

[Marco Helbich]

Dear list,

I've got two autocorrelated datasets and want to perform a two-sample t-test 
comparing the means. Because of the autocorrelation the t-test assumtions 
are violated. In Cliff & Ord (1981, Spatial Processes, Ch. 7.2) I read that 
there is an alternative modified t-test, which considers autocorrelation. Is 
such a test implemented in R or somewhere else? Can anybody give me a 
helping hand?

I appreciate every hint! Thanks.
Marco
