Solution

There are several ways to visualize the relationship between three categorical variables in R. Here are a few examples:

  1. Mosaic Plot: This is a graphical representation of the contingency table or more-dimensional tables. It provides a visual representation of the relationship between two or more categorical variables. In R, you can use the mosaicplot() function to create a mosaic plot.
# Create a contingency table
data <- table(df$var1, df$var2, df$var3)

# Create a mosaic plot
mosaicplot(data, main="Mosaic Plot of Three Categorical Variables")
  1. Stacked Bar Plot: This is another way to visualize the relationship between three categorical variables. In R, you can use the barplot() function to create a stacked bar plot.
# Create a contingency table
data <- table(df$var1, df$var2, df$var3)

# Create a stacked bar plot
barplot(data, main="Stacked Bar Plot of Three Categorical Variables", col=c("red","blue","green"))
  1. Three-dimensional Bar Plot: This is a more complex visualization that can be used to represent the relationship between three categorical variables. In R, you can use the bar3D() function from the rgl package to create a three-dimensional bar plot.
# Install and load the rgl package
install.packages("rgl")
library(rgl)

# Create a contingency table
data <- table(df$var1, df$var2, df$var3)

# Create a 3D bar plot
bar3D(data, main="3D Bar Plot of Three Categorical Variables")

Remember to replace df$var1, df$var2, and df$var3 with your actual variables.
