In GrabSVG: Granularity-Based Spatially Variable Genes Identifications

A function for filtering low expressed genes

Description

A function for filtering low expressed genes

Usage

SpFilter(ExpMat_Sp, Threshold = 5)

Arguments

ExpMat_Sp	A sparse, N x M expression matrix in dgCMatrix class with N genes and M spots
Threshold	A threshold set to filter out genes with a total read count below this specified value

Value

A sparse expression matrix in dgCMatrix class

Examples

# create a sparse expression matrix
Raw_ExpMat <- Matrix::rsparsematrix(nrow = 10000, ncol = 2000, 
density = 0.01, rand.x = function(n) rpois(n, 15))
Filtered_ExpMat <- SpFilter(Raw_ExpMat)
