similar to: Are r2dtable and C_r2dtable behaving correctly?

It is not about "really arge total number of observations", but: set.seed(4711);tabs <- r2dtable(1e6, c(2, 2), c(2, 2)); A11 <- vapply(tabs, function(x) x[1, 1], numeric(1));table(A11) A11 0 1 2 166483 666853 166664 There are three possible matrices, and these come out in proportions 1:4:1, the one with all cells filled with ones being most common. Cheers, Jari

Dear All, I have a problem understanding the difference between the outcome of a fisher exact test and a chi-square test (with simulated p.value). For some sample data (see below), fisher reports p=.02337. The normal chi-square test complains about "approximation may be incorrect", because there is a column with cells with very small values. I therefore tried the chi-square with

Hello R-users, I would like to generate two-way contingency tables with zero in one cell. I tried to use the function r2dtable but I could not force one cell to have zero value. Any Idea? Best regards.. Mahmoud [[alternative HTML version deleted]]

I am currently testing species co-occurrence patterns using null models and the oecosimu() function within the vegan() package. My issue is that none of the methods appear to be the ones that I want. The methods listed are r0, r1, r2, r2dtable, swap, tswap. However, I want to know how to go about implementing fixed row algorithms, as suggested in Gotelli 2000 in Ecology. Also, the null models

Hola, En GitHub estará siempre la última versión, pero también está el paquete en CRAN y puedes instalártelo como cualquier otro paquete ahí disponible...

Hola, Puedes hacerlo sin devtools. Descargas el ZIP del repositorio, lo descomprimes, instalas el paquete que hay en CRAN para tener todas las dependencias instaladas y finalmente instalas el paquete en la versión de GitHub. tmp <- paste0(tempdir(), '/likert.zip') download.file('https://github.com/jbryer/likert/archive/master.zip', destfile=tmp,
