vfsettings

Specifies the structure of a vf object (see <code><a rd-options="" href="/link/vf?package=visualFields&version=0.6.2" data-mini-rdoc="visualFields::vf">vf</a></code>) and information pertaining test patterns and their statistical analysis.

datasets

A collection of tools for analyzing the field of vision. It provides a framework for development and use of innovative methods for visualization, statistical analysis, and clinical interpretation of visual-field loss and its change over time. It is intended to be a tool for collaborative research.

vfsettings function

This structure contains a variable specifying the number of columns with patient and subject data, <code>locini</code> and several sub-structures with relevant information pertaining different pattern of locations and their analysis. Information exists for the test patterns <code>p24d2</code>, <code>p30d2</code>, <code>p10d2</code>, and <code>sgrnfl</code>. Each sub-structure contains three items:<dl class="dl-horizontal">
<dt><code>bs</code></dt><dd>locations that correspond to the ananomical region where the blind spot is. For 24-2, those are locations 26 and 35. There are non for the 10-2</dd>
<dt><code>locnum</code></dt><dd>total number of locations of the testing pattern in which stimuli are presented. For 24-2 there are 54 locations, for 30-2 there are 76, for 10-2 there are 68</dd>
<dt><code>locrPD</code></dt><dd>specifies the rank TD value to be used for the derivation of TD. For 24-2, that ranked location would be 7, corresponding approximately (but not very) to the 85th percentile. For 30-2 the ranked locatoion taken is 10, but this needs fixing???. The way PD is calculated really for 30-2 is by taking the 24-2 locations and finding the seventh largest</dd>
