[R] Export the R object

[Eugene]

If you do a lot of exports from R to excel, you might want to use 
a wrapper function around write.table(). I got tired of using 
write.table(), go to excel, select file and load routine. 

My solution to the problem is to create a simple function that
opens excel spreadsheet automatically from R. The function
exports R data.frame into temp file, and calls excel with temp
filename. It saved me a lot of time. 
 
An example: 
> excel(mymydataframe

Here is the function: ( you might have to change path to the excel 
executable )

excel <- function(x) {
   #create a temp filename
  tmpfilename <-paste(tempfile(c("abs")),".csv",sep="");

   #export table in comma seperated by ,
    write.table(x, file=tmpfilename, sep=",");
	         
   #run excel as a background process
   system( paste('"C:\PROGRAM FILES\MICROSOFT OFFICE\OFFICE\EXCEL.EXE"', tmpfilename ),
wait=FALSE);

   #sleep 5 seconds, this is done to insure that R doesn't delete the file before excel opens it
    Sys.sleep(5);
       unlink(tmpfilename);
}

Hope this helps.
