inzdf: iNZight data frame object

Description

This object allows the data to be either a standard R data.frame or a connection to a database.

Usage

inzdf(x, name, ...)

# S3 method for tbl_df inzdf(x, name, ...)

# S3 method for data.frame inzdf(x, name, ...)

# S3 method for SQLiteConnection inzdf( x, name = deparse(substitute(x)), schema = NULL, var_attrs = list(), dictionary = NULL, keep_con = FALSE, ... )

Value

an inzdf object

Arguments

x

a data.frame or db connection

name

the name of the data

...

additional arguments passed to methods

schema

a list specifying the schema of the database (used for linking)

var_attrs

nested list of variables attributes for each table > variable

dictionary

an inzdict object

keep_con

if `TRUE` data will remain in DB (use for very large data)

Details

TODO: It is possible to specify a linking structure between multiple datasets, and when variables are selected the dataset will be linked 'on-the-fly'. This, when used with databases, will significantly reduce the size of data in memory.
