Join data frame columns
Hi! Either I don't understand what you want to do, or it doesn't make any sense. First, a vector cannot have different modes. If you want a single vector it will most likely be coerced in to characters; probably not what you want. Second, what you do is build a data.frame with another data.frame without doing anything. What is df? Provide the output of dput(df). How do you want new_df to look like? What is the difference with df?

Hi, I have a data frame with 100 variables (numeric and non numeric types), and I want to join them in only one column, like a vector, but i want to keep the non numeric variables like they are. I know that i can do something like this: Suppose that my data is in df variable new_df<-data.frame(c(df[,1],df[,2],df[,3],df[,4],...........) This works but i have 100 variables! Any way of doing this a little bit faster?
