R help - Jul 2009 - How to create a permanent dataset in R.

Hi everybody,

Actually, we know that If we create a dataset in R ,after closing the
session the dataset automatically is closed. I tried for creating dataset
permanently in R.I am facing the problem of creating permanent dataset.
can we create dataset permanently If possible? 
Could somebody help me out in this aspect,plz? Any help would be
appreciated.

Thanks in advance.

Say your dataset is stored in variable "dat".

Type:
> save(dat, file="mydatfile.RData")
Next time you start the session, call:

load("mydatfile.RData")

And you can reload your dataset.

Is this what you meant?

HTH,
Alex

The biggest help would come by not pretending to be Albert Einstein.

(redirecting to r-help; it seems more appropriate for such a question)

I am not sure what exactly you want to do, but you could use
save.image() to save R's workspace and re-load it when re-opening R
via load(). Otherwise you can use Rcmdr or JGR to graphically, that is
via point-and-click, perform these operations.

Or you could just use save.image in your default directory for R and R
will then open it automatically. I'd use that sparingly though; it is
not always a blessing to have old data hanging about...

Hi,
         Thanks for your valuable reply.
can you provide me some more information regarding . Here we are reloading
the data when we start the R, In R there are some default packages with
datasets can we create a dataset permanently in any packages so that we can
get the dataset without reloading,like creating dataset in a permanent
library in SAS .

   can we create our own packages in R. It would be very helpful for us, if
you provide any information regarding this. 

Thanks for your reply in advance

PLEASE!  These are typical quesions of R beginners.

They do  *NOT*  belong to the R-devel mailing list,
but rather to R-help  (and even then: 

    PLEASE do read the posting guide http://www.R-project.org/posting-guide.html
  

)

Again: do *NOT* misuse R-devel with such questions. They do not
belong here at all.
