1. Pie Charts

userName <- c("Lam Wei Wei", "Zheng Da Shi", "Lin Da You", "Fei Gu Man", "Chen Kuang", "Wong wei yun")
salary <- c(8500, 9800, 12500, 15000, 8700, 7500)
jobPosition <- c("Staff", "Manger", "BOSS", "CEO", "Staff", "Staff")
bonus <- c(2300, 1350, 3285, 1035, 3285, 1035)

result <- matrix(salary,ncol=6, byrow=TRUE)

colnames(result) <- userName
rownames(result) <- "salary"
result

pie(result, labels = userName, main="Salary bar chart")

Output result:

       Lam Wei Wei Zheng Da Shi Lin Da You Fei Gu Man Chen Kuang Wong wei yun
salary        8500         9800      12500      15000       8700         7500

2. 3D Pie Chart

library(plotrix)

result <- matrix(salary,ncol=6, byrow=TRUE)

colnames(result) <- userName
rownames(result) <- "salary"
result

pie3D(result,  labels = userName, explode=0.1, main="Salary bar chart")
