These functions allow a '>db.table
or
'>db.view
object to be treated as an environment,
in a manner analogous to data frames.
# S3 method for db.obj
as.environment(x, ...)
# S3 method for db.obj
with(data, expr, ...)
For with
, an R expression to evaluate in the context of a database table or view.
Other arguments; unused.
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.
