The ratio of tumour border cell count and tumour cell count

Source: R/R_BT.R
R_BT.Rd

Calculates the ratio of the tumour border cell count and the total tumour cell count in an image. The tumour border cells are detected by the default identify_bordering_cells function. If the ratio is high, it means that most tumour cells are identified as bordering cells. This means there is no clear tumour clusters.

Usage

R_BT(sce_object, cell_type_of_interest, feature_colname)

Arguments

sce_object

SingleCellExperiment object generated by format_image_to_sce.

cell_type_of_interest

String. The cell type that the user wants to determine a cluster of.

feature_colname

String. The column that contains the cell type of interest.

Value

A number is returned.

Examples

R_BT(SPIAT::defined_image, cell_type_of_interest = "Tumour", "Cell.Type")
