How to perform a calculation in each element of my list?
Hi R-helpers, I have a list containing 10 elements, each of which is a dataframe. I wish to add a new column to each list element (dataframe) containing the product of the last two columns of each dataframe. I'd appreciate any pointers, thanks! Mark Na [[alternative HTML version deleted]]
