Dear All, I have a dataframe which has a few thousand companies with unique company numbers and names and each company has data for several years and each year is stored in a separate row.
I want to get a total for the number of years of data for each company. When I loop through the data with the following command I get a value of ‘1’ rather than a total of the rows for each company
while All_companies$COMPANY_NAME == All_companies$COMPANY_NAME + 1
Can you kindly help me on this?
