seqinr (version 1.0-1)

get.db.growth: Get the exponential growth of nucleic acid database content

Description

Connects to the embl database to read the last release note about the number of nucleotides in the DDBJ/EMBL/Genbank database content. A log-linear fit is represented by dia.bd.gowth() with an estimate of the doubling time in months.

Usage

get.db.growth(where = "http://www.ebi.ac.uk/embl/Documentation/Release_notes/current/relnotes.txt" )
dia.db.growth( get.db.growth.out = get.db.growth(), Moore = TRUE, ... )

Arguments

where

the file containig the database growth table.

get.db.growth.out

the output from get.db.growth()

Moore

logical, if TRUE add lines corresponding to an exponential growth rate with a doubling time of 18 months, that is Moore's law.

...

further arguments to plot

Value

• A dataframe with the statistics from the embl site.
