I can obtain the names of my variables of a data frame with the command "names (df)". It gives say:
#[1] "V1" "V2" "V3"
But I would like to obtain a vector, something like this:
c("V1", "V2", "V3")
Is this possible in R?
Thanks in advance for your response

I'm not sure to understand.names(df)is the vectorc("V1", "V2", "V3"). If you want to printc("V1", "V2", "V3"), you can dodput(names(df)).

It is possible and you can just make a new vector with the names like this:
x <- names(df)
..and the names will be stored in vector x
