scal_var_mat: Generate a matrix of the scaled variance values

In laurenhsu1/corral: Correspondence Analysis for Single Cell Data

Generate a matrix of the scaled variance values

Description

Generate a matrix of the scaled variance values

Usage

scal_var_mat(inp, batchvec = NULL)

Arguments

inp	corralm object or matrix; embedding to compute scaled variances
batchvec	vector; batch labels (can be numeric or char). Defaults to 'NULL', which is appropriate for using a corralm object. If using an embedding matrix for inp, then this argument must be given and length must correspond to number of rows in 'inp'.

Value

matrix of the scaled variance values by PC (batches in rows; PCs in columns)

Examples

dat <- matrix(rnorm(5000), ncol = 50)
bv <- rep(seq(3),c(10,30,60))
scal_var_mat(dat, bv)
