dplyr (version 0.3)

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

Run this code
if (require("Lahman")) {
src_dt("Lahman")

batting_df <- tbl(src_df("Lahman"), "Batting")

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