probabilitiesFromConfusionMatrix R Documentation
Helper function to calculate probability from confusion matrix stats in dplyr friendly manner
Description
The purpose of this is to calculate the probabilities of binary outcomes from
a table of true pos, true neg, false pos and false neg trials
Usage
probabilitiesFromConfusionMatrix(df, tpVar, fpVar, fnVar, tnVar)
Arguments
df
a dataframe containing one observation per row
tpVar
the datatable column containing frequency of cooccurrence of true positives
fpVar
the datatable column containing frequency of occurrence of false positives
fnVar
the datatable column containing frequency of occurrence of false negatives
tnVar
the datatable column containing frequency of occurrence of true negatives
Value
the datatable with additional columns for all the probabilities associated with each outcome (i.e. a 2x2 confusion matrix)
