| Yes, well put Davor.

I forgot to give the URL:

https://r-forge.r-project.org/scm/viewvc.php/pkg/inst/examples/qt/?root=rinside

This reimplements the old 'tkdensity' density estimation with a slider for
the bandwidth with a twist: data generation is an R expression, so I default
to a simple mixture of two normals.
