Create an image set out of a list in the right form containing the values of the 2d functions. Only 2d functions in a rectangular windows are currently supported; the values are provided in matrices (arrays).
create_image_set(image_set, ...)A list containing elements r, obs, sim_m and theo.
r, sim_m and theo are optional, obs needs to be provided always.
If provided, r must be a data.frame describing the argument values
where the images have been observed (or simulated). It must consist of the following two or
four components:
a) "x" and "y" giving the equally spaced argument values for the x- and y-coordinates
(first and second dimension of the 2d functions) where the data have been observed,
b) "x", "y", "width" and "height", where the width and height give the width and height of the
pixels placed at x and y, or
c) "xmin", "xmax", "ymin" and "ymax" giving the corner coordinates of the pixels
where the data have been observed.
If not given, r is set to be a list of values from 1 to the number of first/second dimension
of 2d functions in obs.
obs must be either a 2d matrix (dimensions matching the lengths of r vectors)
or 3d array containing the observed 2d functions (the third dimension matching the number
of functions).
If obs is a 3d array, then sim_m is ignored.
If obs is a 2d array, then sim_m must be a 3d array containing the simulated
images (2d functions) (the third dimension matching the number of functions).
If included, theo corresponds to the theoretical function
(e.g., under the null hypothesis) and its dimensions must either match the dimensions
of 2d functions in obs or it must be a constant.
Do not use. (For internal use only.)
The given list adorned with the proper class name.
