dplyr (version 0.2)

src_local: A local source.

Description

This is mainly useful for testing, since makes it possible to refer to local and remote tables using exactly the same syntax.

Usage

src_local(tbl, pkg = NULL, env = NULL)
src_df(pkg = NULL, env = NULL)
src_dt(pkg = NULL, env = NULL)

Arguments

tbl

name of the function used to generate tbl objects

pkg,env

Either the name of a package or an environment object in which to look for objects.

Details

Generally, src_local should not be called directly, but instead one of the (currently three) constructors should be used.

Examples

src_dt("Lahman")
src_df("Lahman")

batting_df <- tbl(src_df("Lahman"), "Batting")
if (require("data.table")) {
batting_dt <- tbl(src_dt("Lahman"), "Batting")
}
