Sphere function with random noise

This function calculates the Euclidian distance from a point to the origin after a random displacement of its position.

Usage

sphereN(x, sd = 0.1, aggregate = TRUE)

Arguments

• x:

  The coordinates of the point

• sd:

  The standard deviation of the noise to be added to the position of x, a normal distribution with mean zero is used.

• aggregate:

  If aggregate is TRUE the distance is returned, otherwise the size of the projection of the distance among each axis.

Value

The distance from the point x to the origin after a random displacement.
