A package for seismic analysis in R.
I originally wrote this to get SAC (Seismic Analysis Code) binary files into R because the graphing capability of R is so nice. Since I prefer working in R to SAC I've also been slowly porting some of the more common functions in SAC to R that were not previously available. These have mostly been filtering functions. This package supports Butterworth, Bessel, Chebyshev type I and II filters, instrument deconvolution as well as some other basic time series analysis functions that are commonly used in seismology.
