cor.gene_expr: Compute correlation between sample and reference data

In LBMC/wormAge: Real Age Prediction from Transcriptome staging On Reference

Compute correlation between sample and reference data

Description

Computes the correlation between the gene expressions of the sample and the reference data using the cor function ; default correlation index is spearman.

Usage

cor.gene_expr(samp, refdata, cor.method = "spearman")

Arguments

samp	the sample matrix, gene as rows, individuals as columns
refdata	the reference time series matrix, same format as samp
cor.method	method parameter passed on to the cor function

Value

a matrix of correlation scores with samples as columns, refdata as rows

Examples

X <- matrix(stats::rnorm(5000), ncol = 5)
Y <- X + stats::rnorm(5000, sd = .1)
rownames(X) <- as.character(1:1000) -> rownames(Y)

cc <- cor.gene_expr(X, Y)
