oce (version 1.0-1)

lobo-class: Class to Store LOBO Data

Description

This class stores LOBO data.

Arguments

Slots

data

As with all oce objects, the data slot for lobo objects is a list containing the main data for the object.

metadata

As with all oce objects, the metadata slot for lobo objects is a list containing information about the data or about the object itself.

processingLog

As with all oce objects, the processingLog slot for lobo objects is a list with entries describing the creation and evolution of the object. The contents are updated by various oce functions to keep a record of processing steps. Object summaries and processingLogShow both display the log.

Modifying slot contents

Although the [[<- operator may permit modification of the contents of lobo objects (see [[<-,lobo-method), it is better to use oceSetData and oceSetMetadata, because that will save an entry in the processingLog to describe the change.

Retrieving slot contents

The full contents of the data and metadata slots of a lobo object named lobo may be retrieved in the standard R way. For example, slot(lobo, "data") and slot(lobo, "metadata") return the data and metadata slots, respectively. The [[,lobo-method operator can also be used to access slots, with lobo[["data"]] and lobo[["metadata"]], respectively. Furthermore, [[,lobo-method can be used to retrieve named items (and potentially some derived items) within the metadata and data slots, the former taking precedence over the latter in the lookup. It is also possible to find items more directly, using oceGetData and oceGetMetadata, but this cannot retrieve derived items.

Details

A lobo object may be read with read.lobo or constructed with as.lobo. Plots can be made with plot,lobo-method, while summary,lobo-method produces statistical summaries. Data within a lobo object may be retrieved with [[,lobo-method and altered with [[,lobo-method.
