Remove spikes from Raman spectra
Description
Removes spikes from Raman spectra using median absolute deviation computed for signal
differences. See [1] for more details
Usage
prep.spikes(data, width = 5, threshold = 6)
Arguments
data
a matrix with data values
width
width of the moving median filter
threshold
threshold to compare modified z-score value with to detect the spike.
Value
data matrix with processed values
