I am trying to use which function to obtain the index of a value in a dataframe. Depending on whether the value is present in the dataframe or not I am performing further operations to the dataframe.
However, if the value is not present in the dataframe, I am getting an integer(0). How do I check for integer(0)? something like is.na??? Thank you.
