SAGE library comparison objects consists of one data.frames. It stores
a A and an M value which are the log2 average expression and log2
ratio, respectively. It also has a column for the resulting p.values
from sage.test.
read.sage.library.comparison and
write.sage.library.comparison are utility functions to read and
write SAGE library comparisons. compare.lib.pair can be used to
generate SAGE library comparisons.
