Probably you have values <= 0 in dados[[1]]? Hence we are sure it is not a Weibull distribution underlying your data.... Please repair your broken shift key! Uwe Ligges

If they are really 0, they are not from a weibull. If you think they are, there is something wrong with the data. If not, the underlying distribution is another one. Something we cannot know, but you should know what is going on with your data! Uwe Ligges
thank you
