Examples

sticker function will produce a file with dimension exactly for printing according to http://hexb.in/sticker.html

base plot

library(hexSticker)
s <- sticker(~plot(cars, cex=.5, cex.axis=.5, mgp=c(0,.3,0), xlab="", ylab=""),
          package="hexSticker", p_size=20, s_x=.8, s_y=.6, s_width=1.4, s_height=1.2,
          filename="inst/figures/baseplot.png")

The sticker() will generate a figure specified by the filename parameter. The output of the sticker() function is a ggplot object, e.g. the s variable in the above example. Print the object, print(s), will display the image. However, the image may slightly different from the created image file since the graphic device size are different. To solve this issue, hexSticker package provides plot function to preview sticker. Try plot(s) :).

lattice

library(lattice)

counts <- c(18,17,15,20,10,20,25,13,12)
outcome <- gl(3,1,9)
treatment <- gl(3,3)
bwplot <- bwplot(counts ~ outcome | treatment, xlab=NULL, ylab=NULL, cex=.5,
                 scales=list(cex=.5), par.strip.text=list(cex=.5))
sticker(bwplot, package="hexSticker", p_size=20, s_x=1.05, s_y=.8, s_width=2, s_height=1.5,
        h_fill="#f9690e", h_color="#f39c12", filename="inst/figures/lattice.png")

ggplot2

library(ggplot2)

p <- ggplot(aes(x = mpg, y = wt), data = mtcars) + geom_point()
p <- p + theme_void() + theme_transparent()

sticker(p, package="hexSticker", p_size=20, s_x=1, s_y=.75, s_width=1.3, s_height=1,
        filename="inst/figures/ggplot2.png")

image file

imgurl <- system.file("figures/cat.png", package="hexSticker")
sticker(imgurl, package="hexSticker", p_size=20, s_x=1, s_y=.75, s_width=.6,
        filename="inst/figures/imgfile.png")

Google fonts

library(showtext)
## Loading Google fonts (http://www.google.com/fonts)
font_add_google("Gochi Hand", "gochi")
## Automatically use showtext to render text for future devices
showtext_auto()

## use the ggplot2 example
sticker(p, package="hexSticker", p_size=22, s_x=1, s_y=.75, s_width=1.3, s_height=1,
        p_family = "gochi", filename="inst/figures/ggplot2-google-font.png")
