Introduction to emojifont package in R
In this article, we will see how to use emojifont package in R. This package is designed to bring emoji font to R Programming Language.
We will have a look at how to search and print emoji using emojifont package.
Installation:
To install this package type the below command in the terminal.
install.packages(“emojifont”)
Emoji characters in R
Now we have emojifont package installed so we will import it using library(emojifont). To print emoji we will use emoji(“emojiname”) to search emoji we will use search_emoji(“name”), this will return all the related emoji and we will store it as a list and print using emoji().
R
# importing packagelibrary(emojifont)# printing joy emojiemoji("joy")# searching emojilist <- c(search_emoji("joy"))# printing all the emoji's in the listemoji(list) |
Output:
Emoji characters in R
Getting a random sample of emoji
To get random emoji we will be using sample_emoji(x) to get random emoji’s.
R
# importing packagelibrary(emojifont)# getting random sample of emojislist = c(sample_emoji(10))# printing all the emoji's in listemoji(list) |
Output:
random sample of emoji
Emoji in R plot
Method 1: Using Base Plot
plot() is used to plot the chart where x and y are coordinates.
plot(x, y, …)
“…” are the arguments passed to methods like graphicals parameters.
text() is used to draw vectors labels. where x,y coordinates,
text (x, y = NULL, labels = seq_along(x$x), cex = 1, col = NULL, …)
R
# importing packagelibrary(emojifont)# generating random numbers for x-axisset.seed(200)# gets 10 random point on x axis from # seedx <- rnorm(10)# generating random numbers for y-axisset.seed(100)# gets 10 random point on y axis from # seedy <- rnorm(10)# Plotting a blank chart in order to # clear the screen# if any chart is already opened# or the emoji's will overlapplot(x, y, cex = 0)# plotting charttext(x, y, labels=emoji('joy'), cex=3.5, col='red', family='EmojiOne') |
Output:
Method 2: Using ggplot
ggplot() is used to plot chart, where data is our data frame, aes() describes how content will be plotted on the screen.
ggplot(data = NULL, mapping = aes(), …)
R
# importing packagelibrary(emojifont)library(ggplot2)# generating random numbers for x-axisset.seed(200)# gets 10 random point on x axis from# seedx <- rnorm(10)# generating random numbers for y-axisset.seed(100)# gets 10 random point on y axis from# seedy <- rnorm(10)# defining data framedata <- data.frame(x=x,y=y)# plotting chartggplot(data,aes(x, y, color="red", label=emoji('joy'))) + geom_text(family="EmojiOne", size=6) |
Output:
Method 3: Using Geom_emoji
geom_emoji() works as a wrapper for visualizing emoji.
R
# importing packagelibrary(emojifont)library(ggplot2)# plotting emojiggplot() + geom_emoji("joy", color='red') + theme_void() |
Output:
Method 4: Font Awesome
geom_fontawesome() works as a wrapper for visualizing fontawesome.
R
# importing packagelibrary(emojifont)library(ggplot2)# plotting emojiggplot() + geom_fontawesome("fa-desktop", color='black') + theme_void() |
