Hello All, I wanted to perform a fourier transform on high frequency financial data. I have searched and have not found much on this topic for R. I was wondering if anyone has used any libraries for it or have come across any papers I may read. Many Thanks, Neil Gupta [[alternative HTML version deleted]]

Apologies in advance for the basic nature of my question. I've never worked with time series, but I am, at present, dealing with evolution in time of certain scalar quantities. By looking at the plots, scalar quantity vs time, for several of these quantities, I am observing a correlation of "events" happening at specific, non-regularly spaced instants of time. The fact of observing

Dear R-developers community, I have the following generic: setGeneric( name="newsample", def=function(x,y,z,a,b,c,...){standardGeneric("newsample")} And I can build several methods for this generic. One useful thing is to use "newsample" with only one of the 6 arguments listed. At the moment this is what I do: setMethod(

Hi all! Does anyone knows if it exists a "symbolic math" package in R, that allows to compute derivatives, integrals, etc.? Does exist a freeware version of Maple? Cheers, Marco [[alternative HTML version deleted]]

I have been following the discussions on 'Reasons not to answer very basic questions in a straightforward way' with interest as someone who is also new to R and has had similar experiences. As such it with sadness that I note that most seem to agree with the present approach to the responses to basic questions. I must thank those respondants to my own questions who have been helpful, but
