How to control wigglyness of fitted curve (using Matern5/2 kernel)

[las-matthew-bennett]

Hello,

I'm trying to use your package to fit a model to some data (28 points) and I'm wondering if there's an argument to the gpkm() or the Matern52$new() functions that would force the fitted curve to be smoother?

I can't find anything in the docs, but I see from other googling that some parameters do indeed control the smoothness of the curve?

Any help would be appreciated!
Thanks
