id2image {sma} | R Documentation |
The function id2image
converts an id tag of a gene supplied
by a user into a set of image coordinates regarding the location of
the gene being
considered. Conversion of image coordinates to an id tag is performed
by image2id
.
id2image(X, layout) image2id(x, layout)
X |
an integer value representing the id of a particular gene |
layout |
|
x |
a vector of 4 integer elements which make up the image coordinates of the gene. |
The image coordinates of a gene correspond to the gene's grid row and grid column position within a slide, and the gene's row and column position within a grid.
id2image
returns a vector of 4 integer elements which is
the set of image coordinates.
image2id
returns an integer value which is the gene's id tag.
