The R4CouchDB package provides a collection of functions for basic database and document management operations such as add, get and delete.

Note: Check out sofa, from @recology_ another R package to interact with CouchDB.

Note: I added a example of R4CouchDB usage to the (new) CouchDB wiki

The R4CouchDB package is reviewed in the book XML and Web Technologies for Data Sciences with R by Deborah Nolan and Duncan Temple Lang published in 2014 on Springer.

• Thanks to @parisni for the contribution of cdbAddDocS()

Every cdbFunction() gets and returns a list() containing the complete connection setup and the data. With the command

R> conn <- cdbIni()

such a list() can be generated. It contains some default values e.g. the

R> conn$serverName
R> [1] "localhost"

or

R> conn$digits
R> [1] 7

With a database running at http:https://localhost:5984 the R-command:

R> cdbListDB( cdbIni() )

lists the databases available at localhost.

• R4CouchDB can be installed from http:https://cran.r-project.org:

R> install.packages("R4CouchDB")

R> library(R4CouchDB)

• generate a connection object (a simple list()) with:

R> conn <- cdbIni()

• play around with conn

R> conn$queryParam <- "count=10"
R> cdbGetUuidS(conn)$res

• see test session in the example folder
• write a issue

The functions in the tests folder assume a writable CouchDB instance running on http:https://localhost:5984:

$> cd R4CouchDB/tests 
$> R -f run.r
