R: Create an attribute table

aRTdb-createTable {aRT}

R Documentation

Create an attribute table

Description

Creates a new attribute table in the database and returns it. If the table is created from an aRTdb, then its type will be external. In the case of creating it from layers, it can be any type but external.

Usage

## S4 method for signature 'aRTdb':
createTable(object, tablename, ID="ID", length=16)
## S4 method for signature 'aRTlayer':
createTable(object, tablename=NULL, genID=NULL, type="static", ID="ID", link=ID, length=16, itimeatt="time", ftimeatt="time")

Arguments

`object`	Object of `aRTlayer` or `aRTdb` class.
`tablename`	Name of the table.
`ID`	The name of the unique identifier of the table.
`length`	The maximum length of ID instances.
`genID`	Populate the table IDs linking with the layer geometries? Used with static and dynamic attributes tables only (default is TRUE in the case of static tables and FALSE otherwise).
`type`	The type of the table. See `aRTtable-class` for the available types.
`link`	The attribute of the table that links it with the IDs of geometry tables. Usually, the unique identifier of the table is a good option.
`itimeatt`	Initial time attribute name
`ftimeatt`	Final time attribute name. If it is the same as itimeatt (the default), the temporal table has only one temporal attribute.

Details

TerraLib uses some tables in the database, and then you cannot create tables with these names. Names as “Points...”, “Polygons...”, (other geometries), “tempTable” and “te_...” are reserved. Note that names with non letters characters are also prohibited.
