epost uses the Entrez EPost utility to upload primary UIDs to the Entrez History server
or append a list of UIDs to an existing set of UIDs attached to a Web Environment.
Usage
epost(uid, db = NULL, webenv = NULL)
Arguments
uid
(Required) List of UIDs provided as a character or as an esearch
object.
db
(Required if uid is a character vector) Database containing the
UIDs in the input list.
webenv
(Optional) Web Environment. If provided, this parameter
specifies the Web Environment that will receive the UIDs sent by
epost. epost will create a new query key associated with that
Web Environment. The webenv value
Value
An epost object.
Details
epost returns an integer label called a query key and an encoded cookie string
called a Web environment. epost objects can then be used instead of a UID
list in subsequent calls to esummary, efetch, or
elink.
