Convert record of local spatial frequency (from EHA) to sedimentation rate curve
freq2sedrate(freqs,period=NULL,ydir=1,genplot=T,verbose=T)
Data frame containing depth/height in first column (meters) and spatial frequencies in second column (cycles/m)
Temporal period of spatial frequency (ka)
Direction for y-axis in plots (depth,height). -1 = values increase downwards (slower), 1 = values increase upwards
Generate summary plots? (T or F)
Verbose output? (T or F)
