The circlesplot library helps you display proportions between different objects. Say earth is 3.6 times bigger than the moon. How can you visualize that? It would be helpful if you could draw earth and moon with their exact diameter to make your readers aware of the difference in size. This is where the lib comes into play. It plots two circles with the given diameter next to each other, so readers can observe the ratio. Although it is extremely helpful to visualize planets, it can also be used for other things too.

Install the latest version from CRAN:

install.packages("circlesplot")

or the development version from GitHub:

install.packages("devtools")
devtools::install_github("BenSt099/circlesplot")

You can start by plotting the solar system and its planets:

library('circlesplot')
library('viridis')

planets = c('Mercury','Venus','Earth','Mars','Jupiter','Saturn','Uranus','Neptune')
diameter = c(4879.4,12103.6,12756.3,6792.4,142984,120536,51118,49528)

circlesplot(cp_vals=diameter, cp_text=planets, cp_max=4L, cp_title="Planets", cp_color=viridis(8), cp_sort='desc')

The first plot is exported as png, while the second is exported as pdf.

You may see something unexpected in RStudio: When you create the plot and it is displayed in the lower right window (in the plots tab), it seems like that a part of the plot is cut off or it’s displayed very small. This only happens due to the size of the lower right window. Either resize it or use the following r code to save the plot as pdf:

pdf("path/to/your/pdf/plot1.pdf")
circlesplot(cp_vals=diameter, cp_text=planets, cp_max=4L, cp_color=viridis(8), cp_title="Planets", cp_sort='desc')
dev.off()
