I read in a thread in r-help today that the windows device in 2.6 supports transparency, so I tried an example and had some issues. The density plots should be filled with transparent color in the following example (similar to the points), however the color is "fully" transparent. This works in the Cairo device, but not in the windows device. Thanks, --Matt Matt Austin

...,4,6,8,8,8,8). I have a value,for example x<- 4.8. I would like to understand in which sub interval of v is x. In this case, v would be in the sub interval [4,6] that is in the subinterval starting from element j=7 to the element j+1=8. Can we do that with an R command?

Dear friends, Do you know how to calculate the CONCAVE hull of a set of points (2- dimensional or n-dimensional)? is that possible in R? (With a "smoothing" parameter of course).

...good is the prediction, that is how well model fits the Y on B (that is, how well does it predict)? In other words: Y~T,data=A for training Y~T,data=B for predicting I have devised a couple of method based around 1) standard deviation 2) R^2, but I am unhappy with them.

How do people feel about eliminating the list serv in favor of the forum? Or limiting the list serv to news? I have one vendor I work with that has a knowledgebase, a forum, and two mailing lists - with much overlap of topics. It is truly enough to drive you totally crazy. I'm not suggesting anything. Just bringing it up. Geoff
