Hello, I have a quick question about time series methodology. If I want to
display a boxplot of time series data, sorted by period, I can type:
boxplot(data ~ cycle(data));
where data is of class "ts"
Is there a similar method for calculating, say, the median value of each
time step within the series? (So for a monthly data set, calculate median
for all Januarys, all Februarys, all Marchs, etc.)
Thanks,
Tim
