R help - Jul 2007 - How to open an URL using RGtk2

Hi

I am working on R 2.5.0 on window. I am trying to provide a Hyper-link to
the user as a result, I have tried using gtkLinkButton to exercise the
facility, however, i am not able to perform the required task, i.e. when I
clicked on the LinkButton actually nothing happened.

I have gone through the documentation for the same and found that
GtkLinkButtonUriFunc is a function which is require to do something with the
opening of the given URL. Further, I didn't find any other information
regarding this.

Following is my code:

    messlab <- gtkLabelNew(str = "Please wait!", show = TRUE)
    messwin <- gtkWindowNew(type = NULL, show = TRUE)
    messwin$Add(messlab)
    gtkWindowResize(messwin, 250, 60)
    gtkWindowSetTitle(messwin, "Graph Analysis")

....
....
....

    fihor <- gtkHPanedNew(show = TRUE)
    fn <- gtkLinkButtonNewWithLabel("http://cran.r-project.org/",
"Result
Link!")
    messwin$Remove(messlab)
    gtkLabelSetText(messlab, "Result link is ::")
    gtkPanedAdd1(fihor, messlab)
    gtkPanedAdd2(fihor, fn)
    gtkPanedSetPosition(fihor, 100)
    gtkWindowSetTitle(messwin, "Result Link")
    gtkWindowResize(messwin, 380, 60)
    messwin$Add(fihor)

I am confused how to make this link workable on click?

Your replies/suggestions are important to me. Please suggest solution.

Thanks in advance.

Have you installed GtkLibs:

You can find documentation on this by typing help(GtkLinkButtonUriFunc). You
might have to scroll down a little since the so-called "user
functions" are
described in the overview file for a type.

This is the signature for that function:
GtkLinkButtonUriFunc(button, link, user.data)

So you can define such a function like:
uri_hook <- function(button, link, data) browseURL(link)

and set it with gtkLinkButtonSetUriHook(uri_hook, NULL).

A case could be made that this should be set as the default by RGtk2.

Dear list,

I am interested in fitting a Generalized Additive Mixed Model with 
spatially correlated errors to a large, spatially indexed, data set 
(~4000 observations).

My initial analysis was a Generalized Additive Model that included a two 
dimensional smooth term to model spatially correlated effect (i.e. 
s(latitude,longitude)).  The problem is that the residuals of this model 
are still spatially correlated, so it seems that I should use a GAMM in 
which the spatial autocorrelation is modeled explicitly.

The problem is that, as stated in the documentation of the mgcv package, 
my dataset is too large for the gamm function.  Is anybody aware of an 
alternative approach to analyze this data?
