[R] Header of dataframe

[Benjamin Dickgiesser]

Thx for the help but again, this is not what I am looking for. I need
the  "a" to be over the first column e.g.

a    mean    stdev      n
1 645.6125 65.94129 60
2 655.2121 70.64094 60
3 633.3161 80.48620 60
4 650.3897 77.59191 60
5 630.4955 84.98888 60
6 656.2608 66.16100 60
7 666.1775 74.39796 60
8 663.1543 71.10769 60
