Histogram Bin-width Optimization

Description

Method for selecting the bin size of time histograms.

Usage

histss(x, n = 100, plotting = FALSE)

Arguments

x	numeric vector or matrix.
n	maximum number of bins.
plotting	logical; shall a histogram be plotted.

Details

Bin sizes of histograms are optimized in a way to best displays the underlying spike rate, for example in neurophysiological studies.

Value

Returns the same list as the hist function; the list is invisible if the histogram is plotted.

Examples

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)
