How to draw circles in the R programming language. More details: https://statisticsglobe.com/draw-plot...
R code of this video:

set.seed(394567) # Create example data
data ＜- data.frame(x = rnorm(100),
y = rnorm(100))
head(data) # Print example data

plot(data$x, data$y) # Draw Base R plot without circle

install.packages("plotrix") # Install plotrix package
library("plotrix") # Load plotrix package

plot(data$x, data$y) # Draw Base R plot with circle
draw.circle(0, 0, 1)

install.packages("ggplot2") # Install & load ggplot2 package
library("ggplot2")

ggplot(data, aes(x, y)) + # Draw ggplot2 plot without circle
geom_point()

install.packages("ggforce") # Install ggforce package
library("ggforce") # Load ggforce package

data_circle ＜- data.frame(x0 = 0, # Create data for circle
y0 = 0,
r = 1)
data_circle # Print data for circle

ggplot() + # Draw ggplot2 plot with circle
geom_point(data = data, aes(x, y)) +
geom_circle(data = data_circle, aes(x0 = x0, y0 = y0, r = r))

data_circle2 ＜- data.frame(x0 = 1:5, # Create data for multiple circles
y0 = 1:5,
r = 1:5)
data_circle2 # Print data for multiple circles

ggplot() + # Draw ggplot2 plot with multiple circles
geom_point(data = data, aes(x, y)) +
geom_circle(data = data_circle2, aes(x0 = x0, y0 = y0, r = r, col = r))
