rgblur: Helper for 'makecluster' to 3D gaussian blur cluster...

In aproudian2/rapt: Atom Probe Tomography Analysis

Helper for makecluster to 3D gaussian blur cluster positions.

Description

Function which returns a list of coordinates of radial gaussian blurred points with uniform probability to be sent in any direction. This function was written to apply a blur in positions of RCP spaced clusters. The radial distribution is actually "folded normal" due to the fact that r > 0.

Usage

rgblur(n = 1, mean = 0, sd = 1, coords = "rec", method = "r")

Arguments

n	The number of points you want returned
mean	Mean of the regular normal distribution for radius.
sd	Standard deviation for the normal distribution for radius.
coords	Return command. Either "rec" or "sph". See below for more.
method	One of "r" and "xyz". "r" uniformly distributes direction and normally distributes r, while "xyz" normally distributes x, y and z.

Value

If coords = "rec", returns a vector of cartesian coordinates. If coords = "sph", returns a vector of spherical coordinates.
