getRefCor {deltaccd}

Retrieve the reference correlation matrix for circadian gene co-expression.

Description

The pan-tissue reference matrix is based on a fixed-effects meta-analysis of eight circadian transcriptome datasets from mice, as described in Shilts et al. 2018(doi: 10.7717/peerj.4327). The human blood reference matrix is based an analysis of three microarray datasets (manuscript in preparation).

Usage

getRefCor(
  species = c("human", "mouse"),
  tissue = c("pan", "blood"),
  useEntrezGeneId = TRUE
)

Arguments

species

Currently either 'human' or 'mouse'. Only affects the row and column names of the correlation matrix, not the actual values.

tissue

One of either 'pan' or 'blood'.

useEntrezGeneId

If FALSE, row and column names of correlation matrix will correspond to gene symbols (e.g., PER2).

Value

A matrix of Spearman correlation values.
