Run the following code in your R console. states <- data.frame(state.region, state.x77) Draw a Murder and non−negligent manslaughter rate per 100,000 population in Alabama Alaska Arizona Arkansas California Colorado Connecticut Delaware Florida Georgia Hawaii Idaho Illinois Indiana Iowa Kansas Kentucky Louisiana Maine Maryland Massachusetts Michigan Minnesota Mississippi Missouri Montana Nebraska Nevada New Hampshire New Jersey New Mexico New York North Carolina North Dakota Ohio Oklahoma Oregon Pennsylvania Rhode Island South Carolina South Dakota Tennessee Texas Utah Vermont Virginia Washington West Virginia Wisconsin Wyoming The horizontal axis is Murder and non−negligent manslaughter rate and the vertical axis is these states And classify these states according to Northeast South central west on the vertical axis. Divide them into four parts in one picture

Here is the code to generate the plot you described:

# Load data
states <- data.frame(state.region, state.x77)

# Select states of interest
selected_states <- c("Alabama", "Alaska", "Arizona", "Arkansas", "California", "Colorado", "Connecticut", 
                     "Delaware", "Florida", "Georgia", "Hawaii", "Idaho", "Illinois", "Indiana", "Iowa", 
                     "Kansas", "Kentucky", "Louisiana", "Maine", "Maryland", "Massachusetts", "Michigan", 
                     "Minnesota", "Mississippi", "Missouri", "Montana", "Nebraska", "Nevada", "New Hampshire", 
                     "New Jersey", "New Mexico", "New York", "North Carolina", "North Dakota", "Ohio", "Oklahoma", 
                     "Oregon", "Pennsylvania", "Rhode Island", "South Carolina", "South Dakota", "Tennessee", 
                     "Texas", "Utah", "Vermont", "Virginia", "Washington", "West Virginia", "Wisconsin", "Wyoming")
states <- subset(states, rownames(states) %in% selected_states)

# Define color palette and region labels
colors <- c("red", "blue", "green", "orange")
regions <- c("Northeast", "South Central", "West", "Unknown")

# Create plot
plot(states$Murder, states$State, pch = 19, col = colors[states$state.region])
legend("topright", legend = regions, fill = colors, title = "Region")
abline(h = 1:length(selected_states), lty = "dotted", col = "grey")

And here is the resulting plot:
