Current i use the index function to group them under the same machine and follow by a "frequency" function. However, this way it will be very slow,as the column under Mac 1, Mac 2 and Mac 3 need to have the function "index". This get more slower when you have 6K rows of data. How can i do it more efficiently ? |
