Hi, is it possible to use 
custom variogram models in gstat? I have a data set with a hole effect. 
I've been searching the literature and found out that the Bessel model (J type) is the most appropriate (see Webster and Oliver, 2007). gstat has Bessel K. Does anyone knows a solution?

"If we had obeyed our elders, the high priests in our field of science when we were young, if we had relied on them to guide our research, then we should still be grappling with the legacy of John Stuart Mill and Aristotle. No; it is for the young to have their ideas, and for us older ones to allow those ideas to bubble to the surface. We may modify them, channel them, challenge them,  criticize them; but at all events we should encourage them. The young and their ideas are our future." Richard Webster (1994)
