May I suggest you use a more appropriate tool for your search:

RSiteSearch("multiclass classification")

Hi,

I have been searching everywhere for an implementation of those algorithms,
but I have only observed them in Matlab and on the literature.

I noticed a package called 'ada' in CRAN but it is not for multi class. I
would be happy with just Adaboost.m2, Smoteboost over adaboost.m2 or any
other combination that could account for imbalanced multiclass
classification problems.

Thanks!
