RtDbUnits

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 HFA dB units.
    The threshold was determined by post-hoc fit of FoS curves to the data.

This package contains the current version 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 September 2013 it is fully implemented on the Octopus 900 and partially on the Heidelberg Edge Perimeter. Note to use these two machines you will need either the Rhep or OPIOctopus900 packages which require permission from the respective companies to obtain: see the OPI www site. It also has a cousin: the R package visualFields, which has tools for analysing and manipulating visual field data.
