Convert a dataframe to a vector by rows

Question

I have a dataframe with numeric entries like this one  test  lt - data frame x   c 26  21  20   y   c 34  29  28     How can I get the following vector    gt  26  34  21  29  20  28   I was able to get it using the following  but I guess there should be a much more elegant way  X  lt - test 1    for  i in 2 dim test   1        X  lt - cbind X  test i

You can try as vector t test    Please note that  if you want to do it by columns you should use unlist test

You can try this to get your combination   as numeric rbind test x  test y     which will return    26  34  21  29  20  28

c df x  df y    returns  26 21 20 34 29 28   if the particular order is important then   M   as matrix df  c m 1    c 2    c 3      returns 26 34 21 29 20 28    Or more generally   m   as matrix df  q   c   for  i in seq 1 nrow m       q   c q  m i         returns 26 34 21 29 20 28
