I replace values equal to 0 for 0.00001??
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!

GUYS,
I NEED HELP WITH ERROR:
library(MASS)
dados<-read.table("mediaRGinverno.txt",header=FALSE)
vento50<-fitdistr(dados[[1]],densfun="weibull")
Erro em fitdistr(dados[[1]],
densfun = "weibull") :
Weibull values must be> 0
WHY RETURN THIS ERROR? WHAT CAN I DO?
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!
