date format
Hi,
Try:
dat1 <- data.frame(years=rep(1991:1992,12), months=rep(1:12,2),days= rep(1,24))
?dat1$day <- format(as.Date(paste(dat1[,1],sprintf("%02d",dat1[,2]),sprintf("%02d",dat1[,3]),sep="."),"%Y.%m.%d"),"%d.%m.%Y")
A.K.

Dear Users of R, I have a data frame with three column, the first column contains years, the second one months and third one, the days (cbind(yyyy mm dd)). I want to combine them so that i have one column with the date format as (dd.mm.yyyy). Is there a way of doing that. Thanks in advance, Eliza ??? ??? ??? ? ??? ??? ? ???
