Hi, I have three columns T1,T2,T3 where T1 contains names, T2 contains Age and T3 contains Gender. Now, I want to add a new columns, lets say T_ONE which will have concatenation of header T1 with name (for instance, T1 - John, T1 - Brad and so on), T_TWO which will have concatenation of header T2 with age (for instance T2 -- 25, T2 - 35 etc.) In another words, I just want to use my header name in the observations. Please help.
