ExtrapolatefromDictionary: Extrapolate from Dictionary

In sebastiz/EndoMineR_devlop: Functions to mine endoscopic and associated pathology datasets

Description

Provides term mapping and extraction in one. Standardises any term according to a mapping lexicon provided and then extracts the term. Thus is different to the DictionaryInPlaceReplace in that it provides a new column with the extracted terms as opposed to changing it in place

Usage

ExtrapolatefromDictionary(inputString, list)

Arguments

inputString	The text string to process
list	of words to iterate through

Examples

#Firstly we extract histology from the raw report
# The function then standardises the histology terms through a series of
# regular expressions and then extracts the type of tissue 
Mypath$Tissue<-ExtrapolatefromDictionary(Mypath$Histology,HistolType())
rm(MypathExtraction)
