Dear r-users,
I have a code in SPlus which use julian function. What is the similar code
used in R?
define.date1<-function(dt1,mt1,mt2,nn,da)
{ mt2<-mt2+1
start<-julian(mt1, 1, nn, origin=c(month=1, day=1, year=1971))+1
end<-julian(mt2, 1, nn, origin=c(month=1, day=1, year=1971))+da
a<-dt1[start:end,]
am<-as.matrix(a[,5])
}
I have check the Date package in R but not so sure how to adjust it.
Thank you for any help given.
