Average Spectra within Frequency Bands
Description
Given a matrix of spectra, where each row gives the power at each frequency, create banded spectra by averaging across columns within frequency bands.
Usage
1  bandSpectra(spectra, breaks = NULL, labels = NULL, ...)

Arguments
spectra 
A matrix of spectra with numeric column names (as returned by

breaks 
The break points between the frequency bands. 
labels 
Labels for the frequency bands. 
... 
Further arguments passed to cut. 
Value
A matrix of banded spectra.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21  ## apply to arbitrary matrix to average over column groups
M < matrix(1:12, 3, 4)
colnames(M) < 1:4
## aggregate first two and last two columns
## (colnames <= 2, or colnames > 2)
bandSpectra(M, breaks = 2)
## apply to clonidine experiment
data(clonidine)
colnames(clonidine$spectra)
banded < bandSpectra(clonidine$spectra, breaks = c(4, 8, 10, 13, 15, 20, 28),
labels = c("delta", "theta", "alpha1", "alpha2", "not named",
"beta1", "beta2", "gamma"))
## run gslcca
result < gslcca(banded, "Critical Exponential",
time = Time, treatment = Treatment, subject = Rat, separate = FALSE,
subject.smooth = 4, data = clonidine)
