I want to convert rownames in my dataframe into first column



Example intput:



                                        y
species1 3.783584
species2 3.696341
species3 3.968285


Desired output:



       x                                y
species1 3.783584
species2 3.696341
species3 3.968285

          Just assign the row names to a new column:



          df$x <- rownames(df)
          df <- df[,c("x", "y")]


          The second step is only necessary if, for some reason, you care about column order.



          If you also want to revert the row names to the numerical sequence they would have by default, you may do so via:



          rownames(df) <- seq(nrow(df))

          • but that doesn't preserve the the column order. when I do it, it puts column x after column y and still leaves the 1st column row names as is

          df$x <- rownames(df)
