Hello,
This query pertains to manipulation of dates in R. I am new to R and
working on a time series data.
I use the commands,
REAL<-19920101 (say) # 01/01/1992
year<-floor(as.integer(REAL/10000))
year
[1] 1992
tmp<-as.integer(REAL)-year*10000
tmp
[1] 101
month<-floor(tmp/100)
day<-tmp-month*100
month
[1] 1
day
[1] 1
tmp.julian<- julian(month, day, year)
tmp.julian
[1] 8035
dates(tmp.julian)
01/01/92
I wish to have the output as 01/01/1992 and not 01/01/92 ,but i am
unsuccessful and request your help.
Thanking You.
Regards
Amogh

Try this: dd <- as.Date(paste(REAL), "%Y%m%d") format(dd, "%m/%d/%Y") and read the Help Desk article in R News 4/1.
