Introduction

In this post, I introduce 2 new functions in my Python package ‘cricpy’ (cricpy v0.20) see Introducing cricpy:A python package to analyze performances of cricketers which enable granular analysis of batsmen and bowlers. They are

1. Step 1: getPlayerDataHA – This function is a wrapper around getPlayerData(), getPlayerDataOD() and getPlayerDataTT(), and adds an extra column ‘homeOrAway’ which says whether the match was played at home/away/neutral venues. A CSV file is created with this new column.
2. Step 2: getPlayerDataOppnHA – This function allows you to slice & dice the data for batsmen and bowlers against specific oppositions, at home/away/neutral venues and between certain periods. This reducedsubset of data can be used to perform analyses. A CSV file is created as an output based on the parameters of opposition, home or away and the interval of time

Note All the existing cricpy functions can be used on this smaller fine-grained data set for a closer analysis of players

This post has been published in Rpubs and can be accessed at Cricpy performs granular analysis of players

You can download a PDF version of this post at Cricpy performs granular analysis of players

I have also updated the cricpy template with these lastest changes. See cricpy-template

1. Analyzing Rahul Dravid at 3 different stages of his career

The following functions analyze Rahul Dravid during 3 different periods of his illustrious career. a) 1st Jan 2001-1st Jan 2002 b) 1st Jan 2004-1st Jan 2005 c) 1st Jan 2009-1st Jan 2010

import cricpy.analytics as ca
# Get the homeOrAway dataset for Dravid in matches
# Note:Since I have already got the data I reuse the CSV file
#df=ca.getPlayerDataHA(28114,tfile="dravidTestHA.csv",matchType="Test")

# Get Dravid's data for 2001-02

df1=ca.getPlayerDataOppnHA(infile="dravidTestHA.csv",outfile="dravidTest2001.csv",startDate="2001-01-01",endDate="2002-01-01")

# Get Dravid's data for 2004-05
df2=ca.getPlayerDataOppnHA(infile="dravidTestHA.csv",outfile="dravidTest2004.csv", startDate="2004-01-01",endDate="2005-01-01")

# Get Dravid's data for 2009-10
df3=ca.getPlayerDataOppnHA(infile="dravidTestHA.csv",outfile="dravidTest2009.csv",startDate="2009-01-01",endDate="2010-01-01")

ca.relativeBowlerCumulativeAvgWickets(frames,names)

Conclusion

By getting the homeOrAway data for players using the profileNo, you can slice and dice the data based on your choice of opposition, whether you want matches that were played at home/away/neutral venues. Finally by specifying the period for which the data has to be subsetted you can create fine grained analysis.

Hope you have a great time with cricpy!!!
