Two questions please about maanova > sessionInfo() R version 2.9.0 (2009-04-17) i386-apple-darwin9.6.0 locale: en_US.UTF-8/en_US.UTF-8/C/C/en_US.UTF-8/en_US.UTF-8 attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] maanova_1.14.0 Question 1 I enter > ftest.Breed.mix_1000perm081109F1Fs_fdrtest <- adjPval(ftest.Breed.mix_1000perm081109F1Fs, method = 'adaptive') And all is fine I enter > ftest.Breed.mix_1000perm081109F1Fs_fdrtest <- adjPval(ftest.Breed.mix_1000perm081109F1Fs, method = 'stepdown') And I get Error in fdr(x, method) : Need to specify FDR method (stepup, adaptive, stepdown, or jsFDR). To use jsFDR, one needs to install qvalue() package Question 2 I enter > ftest.Breed.mix_1000perm081109F1Fs_fdrtest <- adjPval(ftest.Breed.mix_1000perm081109F1Fs, method = 'adaptive') And all is fine I enter > ttest.Breed.mix_1000perm081109F1Fsweek1_fdr2 <- adjPval(ttest.Breed.mix_1000perm081109F1Fsweek1, method = 'adaptive') And it processes Ok but All of the Fs.adjPvalperm are the same value, 0.999901839 What am I doing wrong?
