RtSigmaUnits

Response times to white-on-white Goldmann Size III targets for 12 subjects.
 The second column is the distance of the stimuli from measured threshold 
 in 'sigma' units.
 The threshold was determined by post-hoc fit of a cummulative gaussian
 FoS curve to the data for each location and subject.
 Sigma is the standard deviation of the fitted FoS.

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). It specifies basic functions that allow many visual field tests to be constructed. As of October 2017 it is fully implemented on the Octopus 900 and partially on the Heidelberg Edge Perimeter, the Kowa AP 7000, the CrewT imo and the Centervue Compass. It also has a cousin: the R package 'visualFields', which has tools for analysing and manipulating visual field data.
