Details

GetTissueCoordinates: Get cell spatial coordinates

Radius: Get the centroid radius

RenameCells: Update cell names

Theta: Get the offset angle

is.finite, is.infinite: Test to see if the centroids are circular or polygonal

length: Get the number of sides for the polygonal centroid

lengths: Generate a run-length encoding of the cells present

subset, [: Subset a Centroids object to certain cells

show: Display an object summary to stdout

Value

GetTissueCoordinates: A data frame with three columns:

• “x”: the x-coordinate

• “y”: the y-coordinate

• “cell”: the cell name

If full is TRUE, then each coordinate will indicate a vertex for the cell polygon; otherwise, each coordinate will indicate a centroid for the cell

Radius The radius of the centroids

RenameCells: object with the cells renamed to new.names

Theta: The offset angle in degrees

is.finite: TRUE if the centroids are polygonal, FALSE if circular

is.infinite: The opposite of is.finite

length: 0 if the centroids are circular, otherwise the number of sides of the polygonal centroid

lengths: An rle object for the cells

subset, [: x subsetted to the cells specified by cells/i

show: Invisibly returns NULL
