In arnejohannesholmin/AJ: Holmins functions, used also for loading all packages by library(AJ)

Description

Returns a logical vector for whether the 2D positions given in 'x' are inside the object specified by 'object', 'center', 'angle' and 'par'.

Usage

inside.object2d(x, object = c("ellipse", "rect"), par = c(1, 1),
  center = c(0, 0), angle = 0, logical = FALSE)

Arguments

x	is a three column matrix representing the x- y- and z-coordinates. If x is a vector, it is considered to be one single 2D point.
object	is string representing the type of object to use. Currently implemented are "ellipsoid" and "cuboid" (may be abbreviated).
par	is a vector of three elements representing the semi axis lengths for ellipsoid and the x-width, y-depth and z-height of cuboid.
center	is a vector of three elements representing the centre position of the object.
angle	is the angle of the major axis of the ellipsoid in the x-y-plane, in the case that object=="ellipsoid".
logical	is TRUE if the output should be locigal instead of numeric.
