histss: 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.

Value

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

Details

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