unable to connect to 127.0.0.1:27017 in R programming language

Question

mangodb<-mongo.create()

This my r code. When I'm creating a connection, it raises the following error:

Unable to connect to 127.0.0.1:27017, error code = 2.

Answer 1

That means that mongodb isn't listening on its default port (27017). Did you start mongodb ? The R package provides an interface to connect to mongodb , but it's your (or the administrator) responsibility to start the mongodb daemon.
