twowayTable(g1, g2, weights = TRUE, paperLens=paperLen())
TRUE
or FALSE
indicating whether paper
size weights should be used. n11
, n12
,
n21
and n22
. These correspond to the number of papers
that cite both genes, the number that cite only gene 1, the number
that cite only gene 2, and the total number of papers minus those
counted in n11
, n21
, n12
, or in the default case
the weighted versions of these quantities.
weights
is
FALSE
this function computes the
number of papers that cite only gene 1, only gene 2, both and
neither. By default, we use the org.Hs.eg.db package to define the set of
papers that are used in the computations. For other organisms, or for more
restricted sets of papers the user will need to supply the
vector paperLens
explicitly.
One can consider papers which cite many genes to be less informative than
those that cite only a few genes. If weights
is TRUE
(the default) then papers are weighted by the inverse of the number
of citations.
