add_emoji: Input an emoji and create a ggplot2 layer to add to an existing plot

Description

Input an emoji and create a ggplot2 layer to add to an existing plot

Usage

add_emoji(emoji, x = NULL, y = NULL, ysize = NULL)

Arguments

emoji

either a codepoint (without \U etc), or the result from emoji_search

x

x value of the emoji center. Ignored if y and ysize are not specified.

y

y value of the emoji center. Ignored if x and ysize are not specified.

ysize

Height of the emoji. The width is determined by the aspect ratio of the original image. Ignored if x and y are not specified.

Details

Use parameters x, y, and ysize to place the emoji at a specified position on the plot. If all three of these parameters are unspecified, then the emoji will be plotted to the full height and width of the plot.

Examples

# NOT RUN {
library(ggplot2)
library(emoGG)

# Put a emoji behind a plot
qplot(x=Sepal.Length, y=Sepal.Width, data=iris, geom="point") +
 add_emoji("1f337")

# Put a silhouette anywhere
posx <- runif(50, 0, 10)
posy <- runif(50, 0, 10)
sizey <- runif(50, 0.4, 2)
p <- ggplot(data.frame(x = posx, y = posy), aes(x, y)) +
            geom_point(color = rgb(0,0,0,0))
for (i in 1:50) {
  p <- p + add_emoji("1f697", posx[i], posy[i], sizey[i])
}
