...before attempting any clustering at all, or I have chosen the wrong variables in the data set. I'm somehow trying to cluster signal amplitudes that are not referred to the same phase values. For instance, if I have two sinusoids sampled at different phase values like: {sin(0), sin(1/4PI), sin(3/2PI)} and {cos(1/8PI), cos(1/2PI), cos(5/2PI)} is it meaningful to cluster the two set of values above or shall I first refer both signals to the same phase in advance of clustering, like: {sin(0), sin(1/4PI), sin(3/2PI)} and {cos(0I), cos(1/4PI), cos(3/2PI)} or: {sin(1/8PI), sin(1/2PI), sin(5/2...

Hello, I have 2D-data on a torus, i.e. they are scattered within [0:2pi) and are supposed to be periodic with period 2pi. Is there a way in R for a kernel density estimation for such data? I found this article http://www.dmqte.unich.it/personal/dimarzio/density46.pdf but a) I don't fully understand the article (my knowledge in statistics is poor) b) I did not un...

...place '1.23' by '1' in the above examples, the result of the unchnaged *pi() functions is 100% accurate, whereas R> sapply(c(cos,sin,tan), function(Fn) Fn(1e45*pi)) [1] -0.8847035 -0.4661541 0.5269043 is "garbage". After all, 1e45 is an even integer and so, the (2pi)-periodic functions should give the same as for 0 which *is* (1, 0, 0). For such very large arguments, the results of all of sin() , cos() and tan() are in some sense "random garbage" by necessity: Such large numbers have zero information about the resolution modulo [0, 2pi) or (-pi,...

In conducting studies of animal orientation and displacement, I need to produce circular histograms of angles (bearings in radians 0-2pi) where the centre of the circle indicates very few observations for a given bin of angles and outwardly concentric circles indicate greater frequencies of observations for a given bin of angles. I'd like not to have to write the function myself but I haven't found exactly what I am looking...
