Dear List, What is the way in R to plot a graph having date time (e.g. format 12/31/2002 13:12) in the x axis and numerical value (e.g. temperature) on the Y-axis ?
If you have your dates as strings, you need to use strptime() to convert that into date-time objects first.
I could not get 'plot()' to do this as X axis values are non-numeric. 'bwplot()' sorts the date values and thereby changes the order of the dates and of Y. The date/time values have to be shown on the X-axis as tick values rotated by 90 deg. as there more than 100 points. I appreciate your suggestions and hints.
