set_eye_strings {eye}

Set list of codes

Description

This sets the list of codes used throughout the eye package for the coding of all kind of stuff. If you want to change recognized codes, this is the place to do it. See examples below how to easily overwrite it. It is important that you must pass them as a character vector!

cases are always ignored, so you don't need to worry about this bit.

Usage

set_eye_strings(
  right = c("r", "re", "od", "right"),
  left = c("l", "le", "os", "left"),
  both = c("b", "both", "ou"),
  iop = c("iop", "gat", "nct"),
  iop_partial = c("pressure"),
  va = c("va", "bcva"),
  va_method = c("etdrs", "snellen", "logmar"),
  va_partial = c("acuit"),
  id = c("pat", "id"),
  eye = c("eye", "eyes"),
  quali = c("nlp", "lp", "hm", "cf"),

Examples

# To expand recognized codes for eyes, e.g. if you want to use French names

# To restore the defaults, simply call set_eye_strings empty
set_eye_strings()
