A similar version of this question has already been asked here, but there was no satisfying answer yet.

I get the following warning for some of my satellite images: Quick-TRANSfer stage steps exceeded maximum (=5000000).

How do people usually deal with this warning?

(I am using the unsuperClass function from the RStoolbox package.)

As of Oct 5, 2018 the package author has fixed this bug in the github version which can be installed using devtools "install_github" function. If that occurs the warning now says "The Harian-Wong algorithm doesn't converge properly. Consider setting algorithm to 'Lloyd' or 'MacQueen' and/or increase nStarts," and the "$model$ifault" will be equal to 4.
