I am new to R and I would like to use it to write a simple code to visualize the Defect removal efficiency for software defect (Fixed defects / Unresolved defects) * 100 based on the priority of the bugs
I have exported some data sample from Jira:
Priority Resolution Created Resolved
P3 Unresolved 28.02.2017 28.02.2017
P3 Unresolved 28.02.2017 28.02.2017
P1 Fixed 27.02.2017 06.03.2017
P2 Fixed 27.02.2017 14.03.2017
P1 Unresolved 24.02.2017 13.03.2017
P1 duplicate 21.02.2017 02.03.2017
P1 Fixed 24.02.2017 07.03.2017
I would like to reshape this table and at the same time do some calculations. This is very easy using excel pivot tables but I would like to script it with R
Expected output:
Resolution P1 P2 P3 Grand Total
duplicate 2 2
Fixed 4 4 1 9
Unresolved 2 2 4 8
Grand Total 8 6 5 19
Also, I would like to see the trend of the resolution (Something like the following)
Dates P1 unresolved P1 fixed P1 DRE, % P2 unresolved P2 fixed P2 DRE, %
date1 5 0 0% 20 3 15%
date1 + 7 6 2 33% 37 4 11%
date1 + 14 9 3 33% 40 4 10%
How this could be achieved by R programming?
These functions from the janitor package mimic Excel's PivotTable:
library(janitor)
dat %>%
tabyl(Resolution, Priority) %>%
adorn_totals(c("row", "col"))
Resolution P1 P2 P3 Total
duplicate 1 0 0 1
Fixed 2 1 0 3
Unresolved 1 0 2 3
Total 4 1 2 7
Data used:
dat <- read.table(text = "Priority Resolution Created Resolved
P3 Unresolved 28.02.2017 28.02.2017
P3 Unresolved 28.02.2017 28.02.2017
P1 Fixed 27.02.2017 06.03.2017
P2 Fixed 27.02.2017 14.03.2017
P1 Unresolved 24.02.2017 13.03.2017
P1 duplicate 21.02.2017 02.03.2017
P1 Fixed 24.02.2017 07.03.2017", header = TRUE)
Here is an answer for the first part using just table. I saved your data into a file in the same directory, comma-separating the values.
data = read.csv('jira_data.csv')
new_data = table(data$Resolution, data$Priority)
new_data = addmargins(new_data)
