mosaicsFit - rlm failed to converge

[Jesper Grud]

Hello

Long since this group has been active, but ill try anyway. Im trying to use mosaics, but i get an error doing fitting saying that rlm did not converge. I tried modifying the code to allow 60 iterations rather than the standard 20, but still the model does not converge. 

Do you have any suggesting as to why this may be? and whether or not it is an issue I should be concerned about?

Best regards

Jesper
