cumulative frequency plots for factors
Dear list, I have a data frame with a number of events (factor) and the times at which they occurred (continuous variable): event time A 10 A 12 B 15 A 17 C 13 ... Is it possible in R to make a plot against time of the cumulative frequency of occurrence of each event? This would be, a raising line for each factor. Regards, Dieter
