Relative noob here, I have a data.frame and simply want to add an explicit
column of names in column 1 of the form
"trial_number01" for row 1, "trial_number02" for row 2 .... etc. It is simply
for visual purposes and to explain data to others. I've tried
Using row.names and other but still no luck, am sure it has been covered but I
can't find it, can you please point me in the right direction?
Thanks
Jim
