Converting factor data into Date-time format
...one column containing some data in 'date and time' format, e.g. 'dd/mm/yyyy hh:mm'. These data were automatically read and saved as 'factor' in R. When I was trying to produce some plots (such as time series) with the above 'date and time' on x-axis, it caused some disodering problem, e.g. 1st of March 2012 is in front of 10th of Feb. 2012 (if the data is from 10th Feb. 2012 to 1st of March 2012). I understand that I might have to convert them from 'factor' to 'date' first, so I tried using 'as.date'. But this method seems only work for data...
