HowManyOverTime: Number of tests done per month and year by indication

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

Number of tests done per month and year by indication

Description

Get an overall idea of how many endoscopies have been done for an indication by year and month. This is a more involved version of SurveilCapacity function. It takes string for the Indication for the test

Usage

HowManyOverTime(dataframe, Indication, Endo_ResultPerformed, StringToSearch)

Arguments

dataframe	dataframe
Indication	Indication column
Endo_ResultPerformed	column containing date the Endoscopy was performed
StringToSearch	The string in the Indication to search for

Details

This returns a list which contains a plot (number of tests for that indication over time and a table with the same information broken down by month and year).

Examples

# This takes the dataframe MyEndo (part of the package examples) and looks in
# the column which holds the test indication (in this example it is called
# 'Indication' The date of the procedure column(which can be date format or
# POSIX format) is also necessary.  Finally the string which indicates the text
# indication needs to be inpoutted. In this case we are looking for all endoscopies done
# where the indication is surveillance (so searching on 'Surv' will do fine).
# If you want all the tests then put '.*' instead of Surv
rm(list = ls(all = TRUE))
ff <- HowManyOverTime(Myendo, "Indications", "Dateofprocedure", ".*")
