Is the package included in any other package? Thanks a lot in advance.

...I really appreciate any help. I have tried to obtain the book this package was based on (Jammalamadaka and SenGupta 2001 Topics in Circular Statistics) but it is not available at any of my university libraries. Here is an example. The values of "x" are directions in degrees of one amphibian over 6 days and I'd just like to simply calculate the mean direction: > x <- c(5.009684,37.814266, 295.722970, 0.000000, 326.463366,242.678840) > radx <- rad(x) > circ.mean(radx) [1] -0.4283351 > deg(-0.4283351) [1] -24.54179 I would just like this number to be conve...

Hi folks, I''m curious how a lookup with a large group of values would be handled in Rails. For example, I have a (contrived) AnimalType filtering a list of many Animals--more than can be presented comfortably in a dropdown box. Therefore I need to either redirect to another screen to select an animal (returning after the selection is made), or show a dialog--modal or otherwise--to
