Creating an easy pie chart from data vectors

R script

# Pie charts can be a memorable way of representing information.

# There are a number of online examples showing how to create pie charts in R.

# For example: http://www.statmethods.net/graphs/pie.html

# Imagine you have survey response data from 100 respondents and your survey answers range from A do D.

# This will draw 100 draws from the LETTERS vector between A and D
response = LETTERS[ceiling(runif(100)^2*4)]

# You would like to now see the pie chart of results you can simply tabulate.
pie(table(response))



# We can see that about half the results are A followed by B then C then D.
