[R] Compare date Oracle with Sys.time

[arun]

Hello,

Not quite understand about ur problem.  Could you dput your data?

The below should be general format to convert to class date

 now_7<-format(Sys.time()-(7*60*60*24), "%Y-%m-%d 00:00:00")
> now_7
[1] "2012-06-29 00:00:00"
> class(now_7)
[1] "character"
now_7_new<-as.Date(Sys.time()-(7*60*60*24), format="%Y-%m-%d %H:%M:%S")
> now_7_new
[1] "2012-06-29"
> class(now_7_new)
[1] "Date"



A.K.

Subject: [R] Compare date Oracle with Sys.time

I would like to import only datas of my table where DATE>today-7days.
But my datas in Oracle are 'dates' and in R are 'characters'.
now_7<-format(Sys.time()-(7*60*60*24), "%Y-%m-%d 00:00:00")
How to do?
