as.environment: Evaluate expressions within the context of a database table or view

Description

These functions allow a '>db.table or '>db.view object to be treated as an environment, in a manner analogous to data frames.

Usage

# S3 method for db.obj
as.environment(x, ...)
    # S3 method for db.obj
with(data, expr, ...)

Arguments

x, data

A '>db.obj object to treat as an environment.

expr

For with, an R expression to evaluate in the context of a database table or view.

...

Other arguments; unused.

Value

For as.environment, the created environment. Note that no data is transferred to the client; all objects in the environment are queries pointing back to the host.

For with, a '>db.Rquery stored query object representing the expression. Use lk, lookat or as.data.frame to execute the query on the host and retrieve its contents.
