Description Usage Arguments Details Value Class hierarchy for epost Generics with methods for epost Slots

“epost” is an S4 class that provides a container for data retrived by calls to the NCBI EPost utility.

epost allows to upload a list of UIDs to the Entrez History Server and returns an integer label called a query key and an encoded cookie string called a Web environment. epost instances can then be used in stead of a UID list in subsequent esummary, efetch, or elink calls.

1	epost(id, db = NULL, WebEnv = NULL)

`id`	(Required) List of UIDs.
`db`	(Required) 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 is usually returned by a previous call to `esearch`, `epost` or `elink`. If no WebEnv parameter is provided, EPost will create a new Web Environment and post the UIDs to query_key 1.

See the official online documentation for NCBI's EUtilities for additional information.
