binSpectra {ChemoSpec} | R Documentation |
Bin or Bucket a Spectra Object
Description
This function will bin a Spectra
object by averaging every
bin.ratio
frequency values, and summing the corresponding intensity
values. The net effect is a smoothed and smaller data set. If there are
gaps in the frequency axis, each data chunk is processed separately. Note:
some folks refer to binning as bucketing.
Usage
binSpectra(spectra, bin.ratio)
Arguments
spectra |
An object of S3 class |
bin.ratio |
An integer giving the binning ratio, that is, the number of points to be grouped together into one subset of data. |
Details
If the frequency range is not divisible by bin.ratio to give a whole number,
data points are removed from the beginning of the frequency data until it
is, and the number of data points removed is reported at the console. If
there are gaps in the data where frequencies have been removed, each
continuous piece is sent out and binned separately (by
binSpectra
).
Value
An object of S3 class Spectra
.
