Hi again,
It seems that you want the modes to be conserved. This is just not
possible; everything will be coerced to characters, as Rui highlighted.
But the question is why do you want to do this? You would loose helpful
information (i.e. modes). Maybe there is a better way to do what you

Hello,
Sorry for my earlier post, I misunderstood what you want.
dat <- data.frame(letters, 1:26)
as.vector(sapply(d, as.character))
Hope this helps,

What i want is to join "num" and "letters" in a single column. Something
like this

Hello,
Use apply/paste.
apply(df, 1, paste, collapse = "") # outputs a vector
Also, df is the name of an R function, you should choose something else,
it can become confusing.
Hope this helps,

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.fr
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(
