Creates a table with baseline IDF stats

Description

This is a summarise operation. for concepts given a set of samples given a dataframe whose grouping defines the concept to calculate IDF stats for

Usage

calculateIdf(groupedDf, sampleVars, countVar = NULL, totalSamples = NA)

Arguments

groupedDf	a dataframe whose grouping defines the "term" for which we calulate the IDF
sampleVars	the column(s) that contains the unique id of a sample, i.e. traditionally a "document" but could be a patient. escaped by vars(...)
countVar	(optional) a field that contains a count. If this is given then it is assumed that the concept & document combinations are unique
totalSamples	if the data is incomplete (not every document has a concept in it then the expected number fo samples can be specified here)

Value
