Histogram Bin-width Optimization
Method for selecting the bin size of time histograms.
histss(x, n = 100, plotting = FALSE)
x |
numeric vector or matrix. |
n |
maximum number of bins. |
plotting |
logical; shall a histogram be plotted. |
Bin sizes of histograms are optimized in a way to best displays the underlying spike rate, for example in neurophysiological studies.
Returns the same list as the hist function; the list is invisible
if the histogram is plotted.

x <- sin(seq(0, pi/2, length.out = 200)) H <- histss(x, n = 50, plotting = FALSE) ## Not run: plot(H, col = "gainsboro") # Compare with hist(x), or hist(x, breaks = H$breaks) # the same ## End(Not run)
