abbreviate: Abbreviate strings or tokens

In decisionpatterns/conformist: Utilities for conforming data to predefined standards

Description

Abbreviates strings by (optionally) tokenizing and matching token against a dictionary

Usage

abbreviate(string, dict = getOption("abbreviations", abbreviations),
  tokenizer = NULL)

Arguments

string	character; string to attempt to abbreviate
dict	dictionary-like object; uses global options 'confirm.abbreviations' or else the abbreviations
tokenizer	character; pattern passed to str_split to split strings with, usually '_' or ' '. If NULL, the default, strings will not be split.

Details

abbreviate works by first finding a list of tokens that occur in the code.

x can be adorned with match modifiers to control the type of match. See lookup for details.

If there is no matching entry for the token in the dictinary, no substitution is used.

Value

character; string with elements matching dict replaced

  string <- c( 'foo bar', 'foo amount', 'amount', 'amount count date' )
   
  # Attempts to abreviate entire string
  abbreviate(string)
    
  # Tokenizes sting and matches against the token
  abbreviate(string, tokenizer=" ")
  
  abbreviate( c('product_year', "dollar_range"), abbreviations, tokenizer = '_')
