Le 28 sept. 06 ? 13:09, Roger Bivand a ?crit :

OK, the file size at least looks correct, and the output of the  
summary
looks good too. By the way, why the load()?

The load is the system response when I click the R.data in the  
project directory

Could you now try plot(xx, axes=TRUE), and then traceback()  
immediately
after the error occurs?

 > plot(xx,axes=TRUE)

Erreur dans plot.window(xlim, ylim, log, asp, ...) :
	'xlim' n?cessite des valeurs finies
De plus : Warning messages:
1: aucun argument trouv? pour min ; Inf est renvoy?
2: aucun argument pour max ; -Inf est renvoy?
3: aucun argument trouv? pour min ; Inf est renvoy?
4: aucun argument pour max ; -Inf est renvoy?

 > traceback()

4: plot.window(...)
3: localWindow(xlim, ylim, log, asp, ...)
2: plot.default(xx, axes = TRUE)
1: plot(xx, axes = TRUE)

===============

If, I put:

 > Xlim

[1] -84 -75

 > Ylim

[1] 33 37

 > plot(xx,axes=TRUE,xlim=Xlim,ylim=Ylim)

give an empty image
========================
But;
spplot(xx,axes=TRUE) seems to product the good image.



Thanks

Roger
