plotFrequencyHistogramOutlierCutoff: Plot frequencies of elapsed times up to a percentile cutoff

Description

Given a column of values or a data frame created by readFileList or readFile, generate a ggplot of a frequency histogram excluding values above a specified percentile

Usage

plotFrequencyHistogramOutlierCutoff(theDf, outlierCutoff)

Value

Returns a ggplot2 plot. This function is intended to be wrapped in a call to plotSaveGG

Arguments

theDf

Either a data frame created by readFile or readFileList or a vector of numeric values (assumed to be elapsed times).
