In TrigosTeam/SPIAT: Spatial Image Analysis of Tissues

Split an image into grid and calculates a metric for each grid square

Description

Calculates a specified metric for each grid tile in the image and plots the metrics for the grid tiles.

Usage

grid_metrics(spe_object, FUN, n_split, ...)

Arguments

spe_object	SpatialExperiment object in the form of the output of format_image_to_spe.
FUN	Variable name specifying the metric to be calculated.
n_split	Integer specifying the number of splits for the calculation of metrics. This number is the splits on each side (e.g. 'n_split' = 3 means the image will be split into 9 tiles.)
...	Arguments of FUN

Value

A list of the metrics of all grid tiles

Examples

grid <- grid_metrics(SPIAT::defined_image, FUN = calculate_entropy, n_split = 5,
cell_types_of_interest=c("Tumour","Immune3"), feature_colname = "Cell.Type")
