Visualization Commands

1. How to load dataset

cricket <- read.csv("C:/Users/User/Downloads/cs.csv")

2. How to view data

View(cricket)

3. To get data from head

To get first 7 rows	To get all rows except last 7
head(cricket,7)	head(cricket,-7)

4. To get data from tail

To get last 7 rows	To get all rows except last 7
tail(cricket,7)	tail(cricket,-7)

5. To summaries dataset

summary(cricket)

6. Creating pie-chart

pie(table(cricket$Country), main = "Pie Chart of the cricket data set of contries", col = c("orange","pink","red","blue","yellow","green","violet"), radius = 1)

7. Plotting Histogram

hist(cricket$Sixes, col=c("green", "red", "blue"), xlab="Number of Sixes", ylab= "Frequncy of Sixes", main="Histogram of Sixes")

8. Plotting Scatterplot

plot(cricket$Fifties~cricket$Hundreds,xlab="Hundreds" ,ylab="Fifties", main="Scatterplot for Hundreds vs Fifties", col=c("blue", "red"),pch=16)

9. Plotting Scatterplot with background theme and symbols

ggplot(data=cricket,aes(y=Fifties,x=Hundreds,col=Country))+geom_point()

10. Plotting Barchart with background theme and symbols

ggplot(data=cricket,aes(x=Hundreds,fill=Country))+geom_histogram(bins=50)

11. Alternative of Histogram

ggplot(data=cricket,aes(x=Hundreds))+geom_freqpoly()
