We cannot reproduce: We do not have "b.txt". See the posting guide.

Why do you specify nrows, ncol and type=numeric?
>> dados2<-as.vector(dados[,1])
Well, as.vector() strips attributes, particularly it removes the
"factor" attributes!
>> model<-svm(scale=TRUE,type=C,dados[,-1],y=dados[,1],kernel=RBF)
type=C and kernel=RBF cannot make sense, I guess you mean
model <- svm(x=dados[,-1], y=dados[,1], scale=TRUE,
type="C", kernel="RBF")

Same as before.
Please do read "An Introduction to R" - particularly on how to specify
arguments in function calls before proceeding.
