Create Hex Sticker in R

I am going to demonstrate on how to create hexagon sticker using R. Thanks to GuangChuang Yu for creating the hexSticker package. I am goint to use the hexSticker package to create a hexagon sticker with the following code step-by-step:

First, install the hexSticker package from CRAN:

install.packages("hexSticker")

Then, load the hexSticker package:

library(hexSticker)

Next, hex sticker can be created using different approaches.

1. using packages such as ggplot2, lattice

2. using image file

ggplot2

library(ggplot2)
p <- ggplot(aes(x = wt, y = mpg), data = mtcars) + 
  geom_point() + 
  theme_minimal() + 
  theme(legend.position = "none") 

p <- p + theme_void() + theme_transparent()

s <- sticker(p, package = "hexSticker", p_size = 10, s_x = 1, s_y = 1, filename = "sticker.png")

plot(s)

sticker() function is used to create the sticker.

• p is the ggplot object
• package is the package name.
• p_size is the size of the sticker.
• s_x and s_y are the x and y position of the sticker.
• filename is the name of the file to save the sticker.
• plot() function is used to preview the sticker.

Image File

image_url <- system.file("figures/cat.png", package = "hexSticker")
s2 <- sticker(image_url, package = "hexSticker", p_size = 20, s_x = 1, s_y = 0.75, filename = "sticker2.png")
plot(s2)

img <- "/Users/joan/Documents/Joan Website/Joan Quarto/Rposts/2024-04-20-create-sticker/joanicon.png"

s3 <- sticker(img, package = "Joan",
        p_family = "wqy-microhei", p_size = 20, p_x = 1, p_y = 1.65, s_x = 1.0, s_y = .85,
        s_width = 0.5, s_height = 0.5, p_color = "blue", p_fill = "pink",
        h_fill = "pink", h_color = "red",
        filename = "s3.png")

Warning in ggplot2::annotate("text", x = x, y = y, size = size, label =
package, : Ignoring unknown parameters: `p_fill`

plot(s3)

• image_url is the path of the image file.
  
• system.file() function is used to get the path of the image file from a package.
  
• p_color is the color of the package name
• p_fill is the fill color of the package name
• h_fill is the fill color of the hexagon
• h_color is the color of the hexagon border

Happy creating sticker~
