Hi, It wasn't my purpose to quote the assignment here, but since my example is crappy I will. So I'am a manager of a supermarket and interested in the average working hours per employee. At http://www.mijnbestand.nl/Bestand-6Z8PB7VNSUHZ.txt this link you can find the dataset. The dataset contains the total number of employees (first 5 columns) together with the number of worked hours (last 5 columns) of the evening filling team of the supermarket over the period 2 Januari 1992 until 2 January 1993 (each row contains the data of one week). Summerize the data as informative as possible for the manager; use graphical and numerical summaries for this. For this you may use the function apply. To load these data you may prefer to use the R-function read.table instead of the function scan.
By graphical summary I thougt of: boxplot, histogram, qqplot By numerical summary I thougt of: 5pointssummary. How can I use apply (because I must use that function) in order to make those summaries?
