Can also choose to select specific neurons along the way and navigate forwards and backwards.

nlscan(neurons, db = NULL, col = "red", Verbose = T, Wait = T,
  sleep = 0.1, extrafun = NULL, selected_file = NULL,
  selected_col = "green", yaml = TRUE, ..., plotengine = "rgl")

Arguments

neurons

a neuronlist object or a character vector of names of neurons to plot from the neuronlist specified by db.

db

A neuronlist to use as the source of objects to plot. If NULL, the default, will use the neuronlist specified by options('nat.default.neuronlist')

col

the color with which to plot the neurons (default 'red').

Verbose

logical indicating that info about each selected neuron should be printed (default TRUE).

Wait

logical indicating that there should be a pause between each displayed neuron.

sleep

time to pause between each displayed neuron when Wait=TRUE.

extrafun

an optional function called when each neuron is plotted, with two arguments: the current neuron name and the current selected neurons.

selected_file

an optional path to a yaml file that already contains a selection.

selected_col

the color in which selected neurons (such as those specified in selected_file) should be plotted.

yaml

a logical indicating that selections should be saved to disk in (human-readable) yaml rather than (machine-readable) rda format.

...

extra arguments to pass to plot3d.

plotengine

the plotting backend engine to use either 'rgl' or 'plotly'.

Value

A character vector of names of any selected neurons, of length 0 if none selected.
