[R] Error in adabag

[greg holly]

Hi all;

Happy new year. I have got the following error

rror in if (nrow(object$splits) > 0) { : argument is of length zero

 when I am running the following codes.

train <- c(sample(1:27,18), sample(28:54, 18), sample(55:81, 8))
 a2011.adaboost <- boosting(median_kod ~ ., data = b[train, ], boos=TRUE,
mfinal = 10,  control = rpart.control(minsplit = 0))

Regards,

Greg
