The set of papers that cite the input Entrez Gene identifiers are
found, and for each of these the number of genes cited in that
paper is computed and returned.
Usage
paperLen(x)
Arguments
x
A vector of Entrez Gene identifiers.
Value
counts
For each paper the number of Entrez Gene identifiers
referred to.
papers
A list of the same length as x, each element
contains the papers that refer to the corresponding Entrez Gene identifier.
Details
This function first finds the set of unique PMIDs associated with the
input set of Entrez Gene IDS. Then for each PMID it finds the number of
Entrez Gene identifiers associated with that paper. The function uses
different sets of variable mappings from the org.Hs.eg.db
package.
If x is missing then all Entrez gene identifiers in the
org.Hs.egPMID are used.
