Hi, thanks for your reply. I attached the example. I tried your suggestion:
data[is.factor(data)] <- lapply(data[is.factor(data)], function(x) as.numeric(as.character(x))) But I still have the var as factors. I'm thinking now, in the txt file the decimals numbers are separated with a coma. Would it be the reason?
