Dear Reader,

Currently Im trying to get a minimal example of the transformations forest working for my research, but the example provided in the help-function does not work. Im getting a variable length error and the same error happens in the 'application' demo.

> tf_cmod <- traforest(m, formula = y ~ horTh | age, control = ctrl, 
+                      ntree = 50, mtry = 1, trace = TRUE, data = GBSG2)

Error in model.frame.default(data, yxonly = TRUE) : 
  variable lengths differ (found for '(yxonly)')

Is there a way to circumvent this? since I would really like to know how to implement a Transformation Forest for my master thesis.

With kind regards,
Floris-Jan
