twowayTable {CoCiteStats} | R Documentation |
This function computes a two way table for comparing co-citation, in PubMed for the two input genes. The values in the table can be adjusted according to either the paper size or the gene size.
twowayTable(g1, g2, weights = TRUE, numPapers, PaperLen)
g1 |
The LocusLink identifier for gene 1. |
g2 |
The LocusLink identifier for gene 2. |
weights |
TRUE or FALSE indicating whether paper
size weights should be used. |
numPapers |
The total number of papers under consideration. |
PaperLen |
A vector of length numPapers containing the
number of citations each paper makes. |
To determine the association between two genes one can use co-citation in the medical literature. This function computes the number of papers that cite only gene 1, only gene 2, both and neither. These are then returned as the entries in a two way table.
A vector of length four, with entries 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
.
