[R] band pass filter

[Matt Shotwell]

nuncio,

If you already have a filter kernel, you can use the filter function. Of
course, convolution filters can be applied directly using the discrete
Fourier transform via the fft function. For an example of filtering
(lowpass) with R, see http://biostatmatt.com/archives/78 , and the
associated R script linked there. Also see the link to a free
downloadable book by Steven Smith, which discusses the DFT and building
filter kernels.
