[R-sig-Geo] Saving a variogram in gstat

[Mauricio Zambrano-Bigiarini]

Hi Carolina,

You can save all the variables of your current session by using 'save.image':

save.image("myVGMsession.RData")

and then load it as before (from Windows or GNU/Linux):

load("myVGMsession.RData")

Kinds,

Mauricio
