Program 13

Write an R program to create multiple dot plots for grouped data , comparing the distribution of variable across different using ggplot2’s position dodge function .

library(ggplot2)
data <- mtcars
data$cyl <- as.factor(data$cyl)
data$gear <- as.factor(data$gear)
ggplot(data, aes(x = cyl, y = mpg, color = gear)) +
  geom_dotplot(binaxis = 'y', stackdir = 'center', 
               position = position_dodge(width = 0.7),
               dotsize = 0.6) +
  labs(title = "Dot Plot of MPG by Cylinder and Gear",
       x = "Number of Cylinders",
       y = "Miles Per Gallon (MPG)",
       color = "Gear") +
 theme_minimal()

Bin width defaults to 1/30 of the range of the data. Pick better value with
`binwidth`.
