Returns a gene-by-comparison matrix of log2 fold changes stored in a VISTA object.
Usage
get_foldchange_matrix(x, sample_comparisons = NULL, genes = NULL)
Arguments
- x
A VISTA object containing differential expression results.
- sample_comparisons
Optional character vector of comparison names. Defaults to all available comparisons.
- genes
Optional character vector of gene identifiers. When omitted, all genes present in row_data(x) are returned.
Value
A numeric matrix with genes in rows and comparisons in columns.
