scaleFreePlot: Visual check of scale-free topology
Description
A simple visula check of scale-free network ropology.Usage
scaleFreePlot(connectivity, nBreaks = 10, truncated = FALSE, removeFirst = FALSE, main = "", ...)
Arguments
connectivity
vector containing network connectivities.
nBreaks
number of breaks in the connectivity dendrogram.
truncated
logical: should a truncated exponential fit be calculated and plotted in addition to
the linear one?
removeFirst
logical: should the first bin be removed from the fit?
main
main title for the plot.
...
other graphical parameter to the plot function.
Details
The function plots a log-log plot of a histogram of the given connectivities, and fits a linear
model plus optionally a truncated exponential model. The $R^2$ of the fit can be considered an index
of the scale freedom of the network topology.References
