binovfcal: Calculates an array of integrated visual fields

In binovisualfields: Depth-Dependent Binocular Visual Fields Simulation

Description

binovfcal calculates an array of integrated visual fields given required parameters.

Usage

binovfcal(leftvf, rghtvf, lefttheta, righttheta, distplanes, pd = NULL,
  gender = NULL, m_xs = seq(-27, 27, length.out = 10), m_ys = seq(21,
  -21, -6), c_xs = seq(-57, 57, 6), db_cutoff = 25)

Arguments

leftvf	A matrix of left monocular visual field
rghtvf	A matrix of right monocular visual field
lefttheta	A number angle of convergence for the left eye in radian
righttheta	A number angle of convergence for the right eye in radian
distplanes	A vector of object distances in mm.
pd	Pupil distance in mm
gender	A string of either "male" or "female"
m_xs	Horizontal coordinates for monocular visual field for the 24-2 pattern
m_ys	Vertical coordinates for monocular visual field for the 24-2 pattern
c_xs	Horizontal coordinates for integrated visual field (from -57 to 57 degree with 6 degree spacing)
db_cutoff	cutoff value default to 25 dB above which the simulated threshold value is returned (NA otherwise) when there threshold value is present only for one eye

Value

An array of binocular visual fields for the distances specified by distplanes vector.

Warning

the value of either pd or gender has to be provided the unit of pd and fixdist must be the same, default to mm.

Examples

rghtvf <- matrix(c(
NA, NA, NA, 30, 30, 30, 30, NA, NA, NA,
NA, NA, 30, 30, 30, 30, 30, 30, NA, NA,
NA, 30, 30, 30, 30, 30, 30, 30, 30, NA,
30, 30, 30, 30, 30, 30, 30, 30, 30, NA,
30, 30, 30, 30, 30, 30, 30,  0, 30, NA,

NA, NA, 30, 30, 30, 30, 30, 30, NA, NA,
NA, NA, NA, 30, 30, 30, 30, NA, NA, NA
), ncol=10, byrow=TRUE)
leftvf <- rghtvf[, 10:1]
binovfcal(leftvf, rghtvf, -.045, .045, c(1000, 1010), pd=62)
