Description

Class for storing the data of a pairwise comparison between two SAGE libraries.

Usage

read.sage.library.comparison(file)
write.sage.library.comparison(x, file=paste(x$name, "sagecomp", sep="."))
compare.lib.pair(lib1, lib2)

Arguments

x,lib1,lib2

A sage library object

file

File name to read or write to
