Dear R People: I have dates as factors in the following:
> poudel.df$DATE [1] 1/2/2011 1/4/2011 1/4/2011 1/4/2011 1/6/2011 1/7/2011 1/8/2011 [8] 1/9/2011 1/10/2011 Levels: 1/10/2011 1/2/2011 1/4/2011 1/6/2011 1/7/2011 1/8/2011 1/9/2011 > I want them to be "regular" dates which can be sorted, etc. But when I did this: > as.character(poudel.df$DATE) [1] "1/2/2011" "1/4/2011" "1/4/2011" "1/4/2011" "1/6/2011" "1/7/2011" [7] "1/8/2011" "1/9/2011" "1/10/2011" and > as.Date(as.character(poudel.df$DATE),"%m/%d/$Y") [1] NA NA NA NA NA NA NA NA NA because the dates do not have leading zeros. There are approximately 30 years of nearly daily data in the entire set. Any suggestions would be much appreciated.
