In scHOT: single-cell higher order testing

Description

Usage

scHOT_buildFromMatrix(
  mat,
  cellData = NULL,
  positionType = NULL,
  positionColData = NULL
)

Arguments

mat	A matrix with rows for genes and columns for cells
cellData	A dataframe or DataFrame object with rows for cells
positionType	A string indicating the position type, either "trajectory" or "spatial"
positionColData	Strings indicate the position information stored in colData. If positionType is "trajectory" then positionColData should be a sortable vector if positionType is "spatial" then positionColData should be a matrix type object.

Value

A scHOT object

Examples

dat <- rbind(rnorm(50), rnorm(50), rnorm(50))
colnames(dat) <- paste0("cell_", 1:ncol(dat))
rownames(dat) <- c("gene_1","gene_2", "gene_2")

scHOT <- scHOT_buildFromMatrix(dat, cellData = data.frame(1:ncol(dat)))
