# Iris data
data(iris)
x      <- subset(iris, select = -Species)
y      <- iris$Species

method <- c("randomForest","svm","pcalda","knn")
pars   <- valipars(sampling="boot", niter = 10, nreps=4)
res    <- maccest(x, y, method=method, pars=pars, comp="anova") 

res
htest <- mc.anova(res$acc.iter)

oldpar <- par(mar = c(5,10,4,2) + 0.1)
plot(htest$tukey,las=1)   ## plot the tukey results
par(oldpar)
