Dear expeRts, I would like to use a oneway_test (from package coin) to test whether two groups differ on various variables. The variables are encoded within a data frame. Unfortunately, I obtained an error, that I don't understand. Could you please help me ?
Example: library(coin) y <- as.data.frame(matrix(rnorm(200), ncol=2)) group <- as.factor(unif(100)) lapply(y, function(var) oneway_test(var ~ group)) Error message is: (in French, my locale) Erreur dans eval(expr, envir, enclos) : objet 'var' introuvable (my personal translation in English) Error in eval(expr, envir, enclos) : object 'var' not found Thank you, Matthieu Matthieu Dubois Post-doctoral fellow Psychology and NeuroCognition Lab (CNRS UMR 5105) Université Pierre Mendès-France BP47 --- 38040 Grenoble Cedex 9 --- France Email: matthieu.dub...@upmf-grenoble.fr Gmail: matth...@gmail.com http://web.upmf-grenoble.fr/LPNC/membre_matthieu_dubois [[alternative HTML version deleted]]
