Get percentile for ONE ACE metric

Description

Function to calculate percentile ranks for summarized data from ONE ACE metric.

Usage

get_percentile(
  df,
  module,
  id_var = "pid",
  var,
  reverse = FALSE,
  norm_dist = "self",
  norm_dist_grade = NULL
)

Arguments

module	user-specified string to be appended in the output colname
id_var	name of subject identifier col in df Note that this function does NOT allow a grouping variable; please only feed data from ONE GROUP AT A TIME into this function. It's better for norming assumptions.
var	name of data col in df. specified as a string
reverse	should percentile scores be calculated in reverse order (smaller number = better rank)? Defaults to FALSE.
norm_dist	which data should the percentiles be normed to? one of the following "self": no norming distribution, percentiles based on data being fed in "ace_t1": based on results from ACE Fall 2016 data "ace_t3": based on results from ACE Fall 2017 data
norm_dist_grade	if specifying an ACE norming distribution, which grade's norms? Grades in T1: "third", "fifth", "seventh". Grades in T3: "fourth", "sixth", "eighth". Specify as ONE OF THESE STRINGS! Will throw error if grade not specified properly

Value

df containing id_var, group_var (if applicable), var, and percentile rank
