src_local: A local source.

In olascodgreat/samife: A Grammar of Data Manipulation

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)

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 constructors should be used.

Examples

if (require("Lahman")) {
batting_df <- tbl(src_df("Lahman"), "Batting")
}
