sphereN function

Sphere function with random noise

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

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.

Returns

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

Examples

sphereN(rep(0, 10))
