set_eye_strings: Set list of codes

In eye: Analysis of Eye Data

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"),
  ...
)

Arguments

right	right eyes
left	left eyes
both	both eyes
iop	IOP codes
iop_partial	partial strings used to find IOP columns
va	VA codes
va_method	VA methods (used to recognize VA columns - when those strings occur "fully", i.e., not as part of sth else)
va_partial	Also used to find VA columns - looking for partial strings
id	patient column codes
eye	eye column codes
quali	quali VA codes
...	currently not used, but might be needed in the future

Examples

# To expand recognized codes for eyes, e.g. if you want to use French names
set_eye_strings(right = c("droit", "od"), left = c("gauche", "og"))

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