Series Progession Analysis

Description

Generation of one-page reports of series progression analyses

• vfspa saves a pdf with one-page reports of series progression analyses

• vfspashiny generates interactive one-page reports of series progression analyses based on Shiny

Usage

vfspa(
  vf,
  file,
  type = "td",
  nperm = factorial(7),
  trunc = 1,
  testSlope = 0,
  ...
)

vfspashiny(
  vf,
  type = "td",
  nperm = factorial(7),
  trunc = 1,
  testSlope = 0,
  ...
)

Arguments

vf	visual field data
file	The pdf file name where to save the one-page reports of single field analysis
type	Type of data to use. It can be 's', 'td', or 'pd'.
nperm	Number of permutations. Default is 7!
trunc	value for the Truncated Product Method (see reference). Default is 1
testSlope	slope, or slopes, to test as null hypothesis. Default is 0. if a single value, then the same null hypothesis is used for all locations. If a vector of values, then (for plr and poplr) each location of the visual field will have a different null hypothesis. The length of testSlope must be 1 or equal to the number of locations to be used in the PLR or PoPLR analysis
...	other graphical arguments

Value

No return value
