Plots Bebie rank TD curve
bebie( tdr, type = "conventional", diff = TRUE, percentiles = TRUE,
correction = TRUE, txtfont = "serif", pointsize = 12, cex = 1 )
a vf
object with the rank TD curve
whether to use a conventional
way to plot the rank TD curve or ghrank
type where the vf
object passed is the reconstructed within-normal TD rank curve. Default is conventional
add absolute td values or differences from mean normal. Default is TRUE
add percentile lines. Default is TRUE
add ranked TD line after correcting for general height difference. Default is TRUE
font of the text with visual-sensitivity values. Default is serif
size of the text with visual-sensitivity values. Default is 12
a numerical value giving the amount by which plotting text and symbols should be magnified relative to the default, which is 1
returns a graph with the Bebie rank TD curve (also known as the cumulative defect curve [1]) if the option diff
is set to FALSE
. If the option diff
is set to true, then it returns the difference between the subject's rank curve and the mean normal curve. To use this option (and the options with percentile = TRUE
), the tables nvtdrank
, perctdrank
, and perctdrankadj
must exist in the nv-object, for the perimeter tperimetry
, the pattern of locations talgorithm
, and thepresentation algorithm tpattern
. See nvsapdefault
