R Programming language - R Pie Chart

In R, you can create a pie chart using the pie() function. The pie() function takes a vector of values to plot, and several optional arguments to customize the appearance of the plot.

Here is a basic example of how to create a pie chart in R:

# Create a vector of values to plot
values <- c(10, 20, 30, 40, 50)

# Create a pie chart of the values
pie(values)

This will create a simple pie chart with slices representing the proportion of each value in the vector.

You can customize the appearance of the pie chart by using the optional arguments of the pie() function. For example, you can change the colors of the slices by setting the col argument:

# Create a pie chart of the values with custom colors
colors <- c("red", "green", "blue", "orange", "purple")
pie(values, col = colors)

You can also add labels to the slices using the labels argument:

# Create a pie chart of the values with labels
labels <- c("A", "B", "C", "D", "E")
pie(values, labels = labels)

You can control the position of the labels using the pos argument:

# Create a pie chart of the values with labels in a different position
pie(values, labels = labels, pos = 3)

You can also explode one or more slices using the explode argument:

# Create a pie chart of the values with one slice exploded
explode <- c(0, 0, 0, 0.1, 0)
pie(values, explode = explode)
