Introduction

In theory, theory and practice are the same. In practice, they’re not.

There are two ways to write error-free programs; only the third one works.

Simplicity does not precede complexity, but follows it.

This post is the 4th and the last part of yorkr padding for the Twenty20s. In this post I look at the top individual batting and bowling performances in the Twenty20s. Also please take a look at my 3 earlier post on yorkr’s handling of Twenty20 matches

  1. yorkr pads up for the Twenty20s: Part 1- Analyzing team“s match performance.
  2. yorkr pads up for the Twenty20s: Part 2-Head to head confrontation between teams
  3. yorkr pads up for the Twenty20s:Part 3:Overall team performance against all oppositions!

The 1st part included functions dealing with a specific T20 match, the 2nd part dealt with functions between 2 opposing teams in T20 confrontations. The 3rd part dealt with functions between a team and all T20 matches with all oppositions. This 4th part includes individual batting and bowling performances in T20 matches and deals with Class 4 functions.

This post has also been published at RPubs yorkrT20-Part4 and can also be downloaded as a PDF document from yorkrT20-Part4.pdf.

You can clone/fork the code for the package yorkr from Github at yorkr-package

A. Batsman functions

1. Get Team Batting details

The function below gets the overall team batting details based on the RData file available in T20 matches. This is currently also available in Github at [yorkrData] (https://github.com/tvganesh/yorkrData/tree/master/Twenty20/T20-matches). The batting details of the team in each match is created and a huge data frame is created by rbinding the individual dataframes. This can be saved as a RData file

setwd("C:/software/cricket-package/york-test/yorkrData/Twenty20/T20-matches")
india_details <- getTeamBattingDetails("India",dir=".", save=TRUE)
sa_details <- getTeamBattingDetails("South Africa",dir=".",save=TRUE)

2. Get batsman details

This function is used to get the individual T20 batting record for a the specified batsman of the country as in the functions below. For analyzing the batting performances the top T20 batsmen from different countries have been chosen.

  1. Virat Kohli (Ind)
  2. DA Warner (Aus)
  3. Umar Akmal (Pak)
  4. BB McCullum (NZ)
  5. EJG Morgan (Eng)

For e.g. Kohli takes <32 deliveries to score 22 runs and for higher number of deliveries scores around 66 runs. Devilliers needs <94 deliveries to score 84 runs and for greater deliveries scores around 109runs

B. Bowler functions

13. Get bowling details

This is currently also available in Github at [yorkrData] (https://github.com/tvganesh/yorkrData/tree/master/Twenty20/T20-matches). The T20 bowling details of the team in each match is created and a huge data frame is created by rbinding the individual dataframes. This can be saved as a RData file

setwd("C:/software/cricket-package/york-test/yorkrData/Twenty20/T20-matches")
