yorkr pads up for Twenty20s:Part 4- Individual batting and bowling performances!

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.

Talk is cheap. Show me the code.

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

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

The list of Class 4 functions are shown below.The Twenty20 features will be available from yorkr_0.0.4

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). However you may have to do this as future matches are added! 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)
nz_details <- getTeamBattingDetails("New Zealand",dir=".",save=TRUE)
eng_details <- getTeamBattingDetails("England",dir=".",save=TRUE)
pak_details <- getTeamBattingDetails("Pakistan",dir=".",save=TRUE)
aus_details <- getTeamBattingDetails("Australia",dir=".",save=TRUE)
wi_details <- getTeamBattingDetails("West Indies",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. The batting scorecard functions from yorkr pads up for the Twenty20s:Part 3:Overall team performance against all oppositions! was used for selecting these batsmen

Virat Kohli (Ind)
DA Warner (Aus)
Umar Akmal (Pak)
BB McCullum (NZ)
EJG Morgan (Eng)
CH Gayle (WI)

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

par(mar=c(4,4,2,2))
batsmanRunsPredict(kohli,"Kohli")
batsmanRunsPredict(warner, "DA Warner")
batsmanRunsPredict(akmal,"U Akmal")

# BB McCullum needs >32 deliveries to score 69+ runs while Gayle needs >28 deliveries to score 67 runs

batsmanRunsPredict(gayle,"CH Gayle")

B. Bowler functions

13. Get bowling details

The function below gets the overall team T20 bowling 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 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")
ind_bowling <- getTeamBowlingDetails("India",dir=".",save=TRUE)
dim(ind_bowling)

## [1] 872  12

aus_bowling <- getTeamBowlingDetails("Australia",dir=".",save=TRUE)
dim(aus_bowling)

## [1] 1364   12

eng_bowling <- getTeamBowlingDetails("England",dir=".",save=TRUE)
dim(eng_bowling)

## [1] 1183   12

sa_bowling <- getTeamBowlingDetails("South Africa",dir=".",save=TRUE)
dim(sa_bowling)

## [1] 995  12

pak_bowling <- getTeamBowlingDetails("Pakistan",dir=".",save=TRUE)
dim(pak_bowling)

## [1] 1186   12

nz_bowling <- getTeamBowlingDetails("New Zealand",dir=".",save=TRUE)
dim(nz_bowling)

## [1] 1295   12

14. Get bowling details of the individual bowlers

This function is used to get the individual bowling record for a specified bowler of the country as in the functions below. For analyzing the bowling performances the following cricketers have been chosen

Ravichander Ashwin (Ind)
SR Watson (Aus)
SCJ Broad (Eng)
Saeed Ajmal (Pak)
Dale Steyn (SA)
NL McCullum (NZ)

ashwin <- getBowlerWicketDetails(team="India",name="Ashwin",dir=".")
watson <-  getBowlerWicketDetails(team="Australia",name="SR Watson",dir=".")
broad <-  getBowlerWicketDetails(team="England",name="SCJ Broad",dir=".")
ajmal <-  getBowlerWicketDetails(team="Pakistan",name="Saeed Ajmal",dir=".")

p6<-bowlerMovingAverage(nmccullum, "NL Mccullum")
grid.arrange(p1,p2,p3,p4,p5,p6, ncol=3)

17. Bowler cumulative average wickets (yorkr_0.0.3)

Interestingly Ajmal and NL McCullum have a cumulative average wickets of around 2.0. Steyn also has a cumulative average of 2.0+

p1<-bowlerCumulativeAvgWickets(ashwin,"R Ashwin")
p2<-bowlerCumulativeAvgWickets(watson, "SR Watson")
p3<-bowlerCumulativeAvgWickets(broad, "SCJ Broad")
p4<-bowlerCumulativeAvgWickets(ajmal, "Saeed Ajmal")

p6<-bowlerCumulativeAvgWickets(nmccullum, "NL Mccullum")
grid.arrange(p1,p2,p3,p4,p5,p6, ncol=3)

18. Bowler cumulative Economy Rate (ER) (yorkr_0.0.3)

Ajmal’s economy rate deteriorates from a excellent rate of 5.5, while Ashwin’s economy rate improves from a terrible rate of 9.0+.

p1<-bowlerCumulativeAvgEconRate(ashwin,"R Ashwin")
p2<-bowlerCumulativeAvgEconRate(watson, "SR Watson")
p3<-bowlerCumulativeAvgEconRate(broad, "SCJ Broad")
p4<-bowlerCumulativeAvgEconRate(ajmal, "Saeed Ajmal")

22. Get Delivery wickets for bowlers

This function creates a dataframe of deliveries and the wickets taken

setwd("C:/software/cricket-package/york-test/yorkrData/Twenty20/T20-matches")
ashwin1 <- getDeliveryWickets(team="India",dir=".",name="Ashwin",save=FALSE)

steyn1 <- getDeliveryWickets(team="South Africa",dir=".",name="Steyn",save=FALSE)
nmccullum1 <- getDeliveryWickets(team="New Zealand",dir=".",name="NL McCullum",save=FALSE)

23. Predict number of deliveries to wickets

#Ashwin takes <12 deliveries for a wicket while Watson takes around 9 deliveries
par(mfrow=c(1,2))
par(mar=c(4,4,2,2))
bowlerWktsPredict(ashwin1,"R Ashwin")
bowlerWktsPredict(watson1,"SR Watson")

#Broad and Ajmal need around 8 deliveries for a wicket
par(mfrow=c(1,2))
par(mar=c(4,4,2,2))
bowlerWktsPredict(broad1,"SCJ Broad")
bowlerWktsPredict(ajmal1,"Saeed Ajmal")

par(mfrow=c(1,2))
par(mar=c(4,4,2,2))
bowlerWktsPredict(steyn1,"D Steyn")
bowlerWktsPredict(nmccullum1,"NL Mccullum")

Conclusion

This concludes the 4 part writeup of yorkr’s handling of Twenty20’s. I will be addding functionsto the ckage to handle IPL matches soon. You can fork/clone the code from Github at yorkr.

Hope you have a great time with my yorkr package!
