This consists of a log of phone calls (we can refer to them by number) and a reason code that summarizes why they called us. This is a typical Chi-Square test: if we assume that two variables are independent, then the values of the contingency table for these variables should be distributed uniformly. When one of the two variables represents time, a line plot can be an effective method of displaying relationship. The categories that have higher frequencies are displayed by a bigger size box and the categories that have less frequency are displayed by smaller size box. So we take the am vector and add 1 to it.
