What does the output $votes from adaboost signify

r
adaboost

#1

Hello,

I have applied

iris.adaboost <- boosting(Species ~ ., data = iris[train, ], mfinal = 10,
                           control = rpart.control(maxdepth = 1)) 

while understanding boosting.A part of the output is shown below:

What do the weights and votes tell us.The last column in votes has some zero entries in the beginning whereas the first column has some zero’s towards the end.The middle column has no zero entry.Why is it so?Is this some sort of a diagonal matrix being created?
