[R] Date

[arun]

Hi,
Try this:
Year<-c("01/2000","02/2000","03/2000")

#If you want to convert it directly to month/year
library(zoo)
as.yearmon(Year,format="%m/%Y")
[1] "Jan 2000" "Feb 2000" "Mar 2000"


#As your intention is to have DD/MM/YYYY format,
 Year1<-paste("01/",Year,sep="")
Year1
[1] "01/01/2000" "01/02/2000" "01/03/2000"

 Year<-as.Date(Year1, format="%m/%d/%Y")

 Year
[1] "2000-01-01" "2000-01-02" "2000-01-03"


dat1<-data.frame(Year1,Stock_Prices=1:3)
> dat1
       Year1 Stock_Prices
1 01/01/2000            1
2 01/02/2000            2
3 01/03/2000            3


dat2<-data.frame(Year,Stock_Prices=1:3)
> dat2
        Year Stock_Prices
1 2000-01-01            1
2 2000-01-02            2
3 2000-01-03            3

A.K.

Hi
I have monthly data and the dates are in MM/YY Format
I need to convert them into DD/MM/YY format by pasting 01 in place of DD to
all the observations in my Year Column

ex:

Year            Stock Prices
01/2000           1
02/2000           2
03/2000           3


I need to convert them to

Year                      Stock Prices
01/01/2000              1
01/02/2000              2
01/03/2000              3
