binovfcal {binovisualfields} R Documentation

## Calculates an array of integrated visual fields

### 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, 30, 30, 30, 30, 30, 30, 30, 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)
```
