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.).
?paste
?colnames
