PlotResolutionTimeByPriority: Plot hours to resolution time by priority

In stevenranney/ispiranteRanney: Functions to analyze Ispirante data

Description

This function plots the chosen value of resolution time (in

hours) and produces a box plot of those values as a function of priority

level.

Usage

PlotResolutionTimeByPriority(dF, resTime = "first")

Arguments

dF	The dataFrame for which to plot resolution time by priority level.
resTime	A character vector that indicates which resolution time to plot. Other values include "full".

Details

Resolution time in all sample dataFrames is factor; this function

converts apparently numeric values to as.numeric

This functions converts values that are nan.0 to NA.

Priority levels in some of the sample data are represented by five

different values: High, Low, Normal, Urgent,

and -. Review of the sample data showed that the - priority

level could not be determined to match any other level.

Boxes in the plot that is produced from this function can help

managers understand the resolution time of priority level. If the

notches in a box overlap the heavy bar (i.e., the median resolution time)

in an adjacent box, then the resolution time for that priority level is not

significantly different than the resolution time in the adjacent plot. This

provides a quick, easy method of determining if priority level really

has an affect on resolution time.

The red dots on a plot indicate outliers in the data set. In the

geom_boxplot documentation, outliers are defined as data points

fall outside of 1.5 * IQR where IQR stands for the "Inter-Quartile

Range" of the data.

Plots are generated by the function ggplot
