opi.implementations

opiDistributor

A general OPI operation of the following methods to: <code>opiInitialize</code>,
<code>opiPresent</code> <code>opiClose</code>, <code>opiSetBackground</code>,
<code>opiQueryDevice</code>

operation

other parameters to pass to the methods

The method <code>opiDistributor</code> searches for the specific
method of a general OPI <code>operation</code>, which depends on the OPI
implementation selected with <code><a rd-options="" href="/link/chooseOpi?package=OPI&version=2.10.1" data-mini-rdoc="OPI::chooseOpi">chooseOpi</a></code>. It returns an error if no
OPI implementation has been selected yet. A catalog of all specific methods are
listed in <code>opi.implementations</code>.

datasets

Implementation of the Open Perimetry Interface (OPI) for simulating and controlling visual field machines using R. The OPI is a standard for interfacing with visual field testing machines (perimeters) first started as an open source project with support of Haag-Streit in 2010. It specifies basic functions that allow many visual field tests to be constructed. As of February 2022 it is fully implemented on the Haag-Streit Octopus 900 with partial implementations on the Centervue Compass, Kowa AP 7000, Android phones and the CrewT IMO. It also has a cousin: the R package 'visualFields', which has tools for analysing and manipulating visual field data.
