density(kernel = "cosine") .. the `wrong cosine' ..
...the one in the literature,
*NOT* the one we have in R now.
Proposition / Possibilities / RFC [= Request For Comments] :
- We CHANGE the behavior of density(* , kernel="cosine")
to use the cosine from the litterature.
- provide the current "cosine" as kernel = "smoothcosine"
{I'd like to keep the possibility of 1-initial-letter abbreviation}
Enhancement (easy, I'll do that):
- We further provide both
Epanechnikov and "quartic" aka "biweight" additionally
in any case.
