Hallo List, I'm trying to implemement a restricted permutation scheme in permutest(). More precisely I have dependence in my data that should be allowed for in the permutation - I simulated the problem in the example of the vegan documentation p.24: library(vegan) data(varespec) ## Bray-Curtis distances between samples dis <- vegdist(varespec) ## First 16 sites grazed, remaining 8 sites

I am now writing an R code to do the systematic permutation test and the random permutation test. And I encountered a couple of problems which I cannot figure them out. At first, whenever I type "permtest" in my R2.6.1, it always shows:"there is no such a function", I tried again and again and eventually I found I have to use "library (BHH2)" before I use "permtest", though it make me very glad, the question is It just works for two samples situation, but does not...

...ndent but observations within each group are not independent, i.e., x1, x2, ..., x_n are not independent; but x's are independent from y's I wonder if randomization test is still applicable to this case. Does R have any function that can do this test for large m and n? I notice that "permtest" can only handle small (m+n<22) samples. Thank you very much, Wenjin

Hi, I want to ue a randomisation test, to compare two sample means, for a small set of data, I've looked at towt.permutation, perm.test and permtest, as well as permTS(), which is the best one to use for such a simple purpose? I know perm.test package isn't used anymore and coins recommended, but reading the manual I couldnt find the function most like it, ore more likely I didn't understand the lingo used to know it's what I wa...

...g species for these variables. MANOVA seems like the appropriate test, but since I'm unsure of how well the data fit the assumptions of equal variance/covariance and multivariate normality, I want to use a permutation test. I've been through CRAN looking at packages boot, bootstrap, coin, permtest, but they all seem to be doing more than I need. Is the following code an appropriate way to test my hypothesis: result.vect <- c() for (i in 1:1000){ wilks <- summary.manova(manova(maxent~sample(max.spec)), test="Wilks")$stats[1,2] result.vect <- c(res.vect,...
