\name{accessionToUID}
\alias{accessionToUID}
\title{A function to convert accession values to NCBI UIDs.}
\description{
Given one or more accession values, this function will attempt to
convert them into NCBI UID values.
}
\usage{
accessionToUID(...,db=c("genbank","pubmed"))
}
\arguments{
\item{...}{Accession numbers to be transformed.}
\item{db}{Which database this accession number refers to, defaults to Genbank}
}
\details{
Utilizes the PubMed tool esearch.fcgi to convert an accession number
into a valid NCBI UID number.
WARNING: The powers that be at NCBI have been known to ban the IP
addresses of users who abuse their servers (currently defined as less
then 2 seconds between queries). Do NOT put this function in a type
loop or you may find your access revoked.
}
\value{
Returns either a valid NCBI UID value or NULL (if there was nothing
available).

\examples{
## The two returns from genbank should be the same
xdoc <- genbank("U03397",type="accession",disp="data")
x <- accessionToUID("U03397",db="genbank")
xdoc <- genbank(x, type="uid",disp="data")
## Can handle multiple inputs
y <- accessionToUID("M16653","U892893",db="genbank")
