do faster ANOVAS
...ze 1 ANOVA per timepoint and per attribute, there are 101 timepoints and 8 attributes so I want to realize 808 ANOVAS. This will be an ANOVA with two factors : Here is one example: Aov(t1~Subject*Product,data[data$attribute==”A1”,]) I want to store for each ANOVA SSprod,SSsujet,SSerreur,SSinter and SStotal. In fact I want the result in several matrices: Ssprod matrice: T1 t2 t3 t4 … t101 A1 ssprod(A1,T1) A2 A3 … A8 So I would like a matrice like that for ssprod, ssujet,sserreur,ssinter and sstotal. And this is for one permutation, and I want to do 1000 permutations Here is my code: SSmatrixglobal<...

Scheirer-Ray-Hare
Hello to all the people in the forum, I'm trying to perform a Scheirer-Ray-Hare test in R, and despite I've found some posts talking about this test, there no one in which I can found how to do so. Can anyone explain me how to do the test? Thanks Pablo -- View this message in context: http://r.789695.n4.nabble.com/Scheirer-Ray-Hare-tp3818476p3818476.html Sent from the R help mailing

fixed effects
dear R wizards: X is factor with 20,000*20=800,000 observations of 20,000 factors. I.e., each factor has 20 observations. y is 800,000 normally distributed data points. I want to see how much R^2 the X factors can provide. Easy, right? > lm ( y ~ X) and > aov( y ~ X) Error: cannot allocate vector of size 3125000 Kb is this computationally infeasible? (I am not an expert, but

What is the formula of Pseudo-F statistic in capscale in vegan?
...lowing formula to calculate the pseudo-F for a sequential test of significance (equation 4.3, Anderson, Gorley, and Clarke 2008, Chapter 4. Pg. 129, and based on pseudo-F equation in Legendre and Anderson (1999), Ecological Monographs vol. 69): F= (SSFull - SSReduced)/(qFull-qReduced) (SSTotal-SSFull)/(N - qFull - 1) (3) R code ## creating Bray-Curtis of Biodiversity data H.BC <- vegdist(H.Full [,14:211], "bray") ## Distance based redundancy analysis (dbRDA) m1<-capscale(H.BC ~ GroupSize + Board + MtgStyle + DmStyle + DifView + VolAuton, SScomp [,14:19], distance...
