Hi,

I'm Roslina, PhD student of University of South Australia, Australia
from school Maths and Stats. I use S-Plus before and now has started
using R-package. I used 

to analyse rainfall data using julian date. Is there any similar 

function that you can suggest to me to be used in R-package? Thank you 

so much for your attention and help. 

Here are some of my codes:

# dt1-data 

# mt1-begin month, mt2- end month, nn=year, n= no of years

# da - days in the following month

# yr1 - year begin

 

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])

}

 

seq.date1<-function(dt1,mt1,mt2,n,yr1,da)

{ yr1<-yr1-1

   for (i in 1:n)

   {  kp1<-define.date1(dt1,mt1,mt2,yr1+i,da)

       if (i==1) kp2<-kp1

       else kp2<-rbind(kp2,kp1) 

   }

   kp2
