I want to plot a graph using R, to show that very few classes has maximum
best performers. can someone guide me for this? I tried using cumulative
frequencies and then plotting a graph but it does not serve the purpose.
Hi Sunita,
Maybe this will do what you want:
sundat
class_no best_performers
1 101 10
2 102 21
3 103 1
4 104 3
5 105 5
6 106 190
library(plotrix)
staircase.plot(sundat$best_performers,
labels=paste("Class",sundat$class_no),
inc.col="blue",direction="s",
totals=c(TRUE,rep(FALSE,dim(sundat)[1]-1)),
main="Best performers by class")
Jim
