datetime - How to decompose the data of date in R? -

In R, I have followed the data class of the date:

  20100701 20100702 Year, month and day data in 20100703  P> 3 column.   
 
 
 Just to mention, this can also be done by  base  Can be done with  strptime  and  format.POSIXct  (although the package may be less easily than  lubridate ) package:  
  x & lt; -c (20100701,20100702,20100703,20100704) striptime (x, format = "% Y% m% d") - & gt; Y data.fr (year = format (y, format = "% Y"), month = format (y, format = "% m"), day = format (y, format = "% d")) year month day 1 2010 07 01 2 2010 07 02 3 2010 07 03 4 2010 07 04
