Calculates overlaps between three data.frame objects of expression with `padj` and `log2FoldChange` values to determine signatures.

ExpressionOverlapsTable(df.list, padj.threshold = 0.1,
  lfc.threshold = log2(1.5), return.mat = TRUE, reducemat = FALSE)

Arguments

df.list

named list data.frame objects with `log2FoldChange` and `padj` columns

padj.threshold

significance threshold for padj values

lfc.threshold

significance threshold for log2FoldChange values

return.mat

returns a matrix of overlaps; if false, returns list of intersections

reducemat

returns a reduced version that collapses Up and Down into just "Dependent"

Value

matrix by default, or list of intersections
