Dear R-list, Is there any way I can extract part or whole column name from two variables and combine them? Not values, but column names. For example, I have data set with 70 variables. The column names are "Alfalfa", "Corn","Soybean",..."Sunflower". After I combine the two variable (say Alfalfa and Corn), I want to rename it as "AlfCor" or "AlfalfaCorn" automatically not manually. In excel, I found the function combining two texts in individual columns using (=A1&B1, if you want to combine texts in the two cells.).
