R help - Jan 2008 - need help

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

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

Rosalina,

You should start by reading the Posting Guide - it has helpful advice on 
how to solve a problem yourself and how to craft postings to get good 
answers.

The Posting Guide says:

 	[some basics deleted]

Do your homework before posting: If it is clear that you have done basic 
background research, you are far more likely to get an informative 
response. See also Further Resources further down this page.

     * Do help.search("keyword") and apropos("keyword") with
different
       keywords (type this at the R prompt).

and doing exactly that on my system yields:


--------------------------------------------------------------------
Help files with alias or concept or title matching .julian. using fuzzy 
matching:

mdy.date(survival)                  Convert to Julian Dates



Type 'help(FOO, package = PKG)' to inspect entry 'FOO(PKG)
TITLE'.
---------------------------------------------------------------------


which should be enough to get you going.

Also, you will want to consult Rnews which had an informative article on 
handling dates a few years back.

HTH,

Chuck

Good afternoon,

I've installed R on Suse 10.3 compiling the source files. I opne the program
on shell configuration and i have a problem saving the workspace and *.R or
*.Rdata files. I 've read the manual and written the comand as it says but
the output is:

save.image()
Errore in gzfile(file, "wb") : impossibile aprire la connessione
Inoltre: Warning message:
In gzfile(file, "wb") : impossibile aprire il file compresso
'.RDataTmp'


an output error. So i've tried in windows, but i've had the same
problem.

How could i save the data and the files in R?
I apologize for my english but it'not my language.

Thanks a lot to everybody
