Extractor: Extracts the columns from the raw report

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

Description

This is the main extractor for the Endoscopy and Histology report. This depends on the user creating a list of words or characters that act as the words that should be split against. The list is then fed to the Extractor in a loop so that it acts as the beginning and the end of the regex used to split the text. Whatever has been specified in the list is used as a column header. Column headers don't tolerate special characters like : or ? and / and don't allow numbers as the start character so these have to be dealt with in the text before processing

Usage

Extractor(inputString, delim)

Arguments

inputString	the column to extract from
delim	the vector of words that will be used as the boundaries to extract against

Examples

# As column names cant start with a number, one of the dividing
# words has to be converted
# A list of dividing words (which will also act as column names)
# is then constructed
mywords<-c("Hospital Number","Patient Name:","DOB:","General Practitioner:",
"Date received:","Clinical Details:","Macroscopic description:",
"Histology:","Diagnosis:")
Mypath2<-Extractor(PathDataFrameFinal$PathReportWhole,mywords)
