datetime on x-axis of plot
...reading Time Series Analysis and its Applilcations with R Examples and I have a question... I notice that in the book there are timeseries plots but without the x-axis being labeled with dates. They are just numbers 1,...50,...100, etc. How do I get the date to show up on the x-axis? Here is my dateframe: > head(myData, 5) 1 2008-01-30 08:30 7.00 2 2008-01-30 08:32 9.25 3 2008-01-30 08:34 5.50 4 2008-01-30 08:36 5.00 5 2008-01-30 08:38 -26.25 (Also, I have searched using Rseek.org and not found anything to help me. Any searching advice would be greatly appreciate...
