Dear colleagues (especially those with an understanding of the inner workings of R), For some years, I have been using R's fft (Fast Fourier Transform) routines from within C code as part of an R package. With R-3.0.1, fft_factor and fft_work are no longer available as entry points declared in R_ext/Applic.h and this is documented in the Changelog but I lack the skill/knowledge to track down the reason for the change. Does anyone know if (i) there is an alternative route to the fft routines; (ii) there is a reason not to use them; (iii) one should use some other routines instead? Thanks for any help given, Peter Craig -- #--------------------------------------------------------------------# | E-mail: P.S.Craig at durham.ac.uk Telephone: +44-191-3343076 (Work) | | Fax: +44-191-3343051 +44-191-3737415 (Home) | | | | WWW: | | | | http://www.dur.ac.uk/research/directory/staff/?mode=staff&id=455 | | | | Snail: Peter Craig, Dept. of Math.
