p-value for the pointwise significance tests that slopes are lower than (or greater than) a specified reference (typically zero)
S-statistics calculated for the permutation of visual fields
number of locations in the visual field to be analyzed. For 24-2, it is 52 (54 minus the locations in the blind spot). Default is 52.
Whether or not to show histogram x-labels. Default is TRUE.
Graphics parameter plt. Default is c( 0, 1.0, 0.3, 1 )
Graphics parameter mpg. Default is c( 1.85, 0.5, 0 )
font of the text with visual-sensitivity values. Default is sans
size of the text with visual-sensitivity values. Default is 10
Histogram color. Default is rgb( red = 1.0, green = 0.0, blue = 0.0 )
Text color. Default is rgb( red = 1.0, green = 0.0, blue = 0.0 )
