ncbiRelease: NCBI revision history
In cstubben/genomes2: Genome sequencing project metadata

Description Usage Arguments Details Value Author(s) Examples

Returns the date a sequence was first seen at NCBI using the revision history display.

1	ncbiRelease(ids, db="nuccore", common=TRUE, random=20)

`ids`	A vector or comma-separated list of sequence accessions or GI numbers
`db`	Entrez sequence database to search, default nuccore
`common`	If replaced sequences are found, search for the earliest date in the common revision history
`random`	The number of replaced sequences to search

Searches the revision history display and parses the line listing the date a sequence was first seen at NCBI. In some cases, a sequence replaces earlier IDs and if the common option is TRUE, the earliest date of the replaced sequences is returned instead. Also, since a sequence accession may replace 500 or more ids, a random sample of the replaced sequences will be checked.

A data frame listing the accession, release date, and whether replaced sequences are found
