Examples

## Not run: 
X <- iris[, 1:(ncol(iris)-1)]
true.y <- iris[, ncol(iris)]

rf.iris <- randomForest(X, true.y, ntree=30)
es.rf <- set.eSatisfactory(forest.rf, ntree = 30, epsiron = 0.3, resample = TRUE)
tweaked <- tweak(es.rf, newdata= X.test, label.from = "spam", label.to = "nonspam",
                 .dopar = TRUE)

plotSuggest(tweaked, k = 1)
plotSuggest(tweaked, k = 1, .ordered = TRUE, .nonzero.only = TRUE)
