Extract a log2 fold-change matrix — get_foldchange_matrix • VISTA

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.

Examples

v <- example_vista()
mat <- get_foldchange_matrix(v)
dim(mat)
#> [1] 123   1
