avesd: Compute the Average Standard Deviation for a Set of Spectra and
a Given Cutoff Point
Description
Compute the Average Standard Deviation for a Set of Spectra and
a Given Cutoff Point
Usage
avesd(Ma, cutoff)
Arguments
Ma
A matrix with rows the m/z values and columns samples/spectra
cutoff
A number of m/z
Value
A real number.
Details
For a given cutoff point, the standard deviation of all spectra will be
calculated at each m/z above this cutoff point. The resulting sd's are
then averaged and returned.
