How to draw concentric circles with dark borders in R?

To draw concentric circles, we can use draw.circle function of plotrix package where we can put lwd argument but firstly we would need to create a blank graph with plot function as shown below.

For Example, we can create three concentric circles at position X=5 and Y=5 having radius of 1, 2, and 3 by using the below command −

draw.circle(5,5,c(1.5,1,0.5),col=c("yellow","green","orange"),lwd=2)

Example

Consider the following snippet −

plot(1:10,type="n")

Output

If you execute the above given snippet, it generates the following Output −

Add the following code to the above snippet −

plot(1:10,type="n")
library(plotrix)
draw.circle(5,5,c(1.5,1,0.5),col=c("yellow","green","orange"))

Output

If you execute all the above given snippets as a single program, it generates the following Output −

Add the following code to the above snippet −

plot(1:10,type="n")
library(plotrix)
draw.circle(5,5,c(1.5,1,0.5),col=c("yellow","green","orange"))
draw.circle(5,5,c(1.5,1,0.5),col=c("yellow","green","orange"),lwd=2)

Output

If you execute all the above given snippets as a single program, it generates the following Output −

Add the following code to the above snippet −

plot(1:10,type="n")
library(plotrix)
draw.circle(5,5,c(1.5,1,0.5),col=c("yellow","green","orange"))
draw.circle(5,5,c(1.5,1,0.5),col=c("yellow","green","orange"),lwd=2)
draw.circle(5,5,c(1.5,1,0.5),col=c("yellow","green","orange"),lwd=5)

Output

If you execute all the above given snippets as a single program, it generates the following Output −
