1. I know that duplicate times are not allowed but my data has them. What do I do? | 2. When I try to specify a log axis to plot.zoo a warning is issued. What is wrong? | 3. How do I create right and a left vertical axes in plot.zoo? | 4. I have data frame with both numeric and factor columns. How do I convert that to a "zoo" object? | 5. Why does lag give slightly different results on a "zoo" and a "zooreg" series which are otherwise the same? | 6. How do I subtract the mean of each month from a "zoo" series? | 7. How do I create a monthly series but still keep track of the dates? | 8. How are axes added to a plot created using plot.zoo? | 9. Why is nothing plotted except axes when I plot an object with many NAs? | 10. Does zoo work with Rmetrics? | 11. What other packages use zoo? | 12. Why does ifelse not work as I expect? | 13. In a series which is regular except for a few missing times or for which we wish to align to a grid how is it filled in or aligned? | 14. What is the difference between as.Date in zoo and as.Date in the core of R? | 15. How can I speed up zoo?
