I have a large data set with information in the first few columns that is just strings, then the columns that I need to sum, and then more information that is just extra but is values as well.
So, if there is 25 columns, I need to sum the information per row for columns 5-11.
I think a good solution might be to create a new column and sum the information per row into the new column but I can't seem to find a code that only sums specific columns in the row.
Any help would be appreciated!
