emoji on Mac

[gav888]

Emoji would not show up using Rstudio 1.2.5001 with R 3.6.1 on Mac Os.

Thank you

Not entirely sure what your problem is here as there are a number of ways to look at the emojis in RStudio. Do you mean in the Console? The output you should get there would look like this:

library("rwhatsapp")
library("dplyr")
library("tidyr")
chat <- rwa_read(system.file("extdata", "sample.txt", package = "rwhatsapp"))
chat %>% 
  select(emoji, emoji_name) %>% 
  unnest(cols = c(emoji, emoji_name))
#> # A tibble: 332 x 2
#>    emoji                  emoji_name                     
#>    <chr>                  <chr>                          
#>  1 <U+263A>                     smiling face                   
#>  2 "\U0001f44c\U0001f3fb" OK hand: light skin tone       
#>  3 "\U0001f605"           grinning face with sweat       
#>  4 "\U0001f600"           grinning face                  
#>  5 "\U0001f603"           grinning face with big eyes    
#>  6 "\U0001f604"           grinning face with smiling eyes
#>  7 "\U0001f601"           beaming face with smiling eyes 
#>  8 "\U0001f606"           grinning squinting face        
#>  9 "\U0001f605"           grinning face with sweat       
#> 10 "\U0001f602"           face with tears of joy         
#> # ... with 322 more rows

In the Viewer (View(chat)) you should be able to see actual emojis in the text column (but not in the emoji column as this is a list which is rendered a little differently):

If you follow my vignette (vignette("Text_Analysis_using_WhatsApp_data", package = "rwhatsapp")) you should also be able to see emojis in the plots.

Which of the above causes trouble for you? Or are you trying to do anything not covered above?

Hi there, thanks for the quick reply. I cannot see the emoji when plotting their frequencies by user in the plot window using Rstudio. Attached what I see.

But otherwise your output is the same as above?

[gav888]

Yes, only in the plot emoji are showing up.

I think that the problem here is that the default font for ggplot2 on macOS does not support emoji characters (It looks good on Linux and OK on Windows). See this SO question and answer. It would be great if you or anyone reading this could test the solution with the emojifont package and let me know if it works. I could then add a note to the readme and vignette.

I recently came across a blog post by someone using the package. He found a cool way to get around the problem, namely looking up pngs and including them in the plot via ggimage. I like the idea and just pushed an update to the package which makes looking up the pngs easier. Here is how this would look like (only works with newest GitHub version so far):

library(rwhatsapp)
library(dplyr)
library(tidyr)
library(ggplot2)
library(purrr)
library(ggimage)

chat <- rwa_read(system.file("extdata", "sample.txt", package = "rwhatsapp"))

emojis <- emojis %>% # data built into package
  mutate(emoji_url = paste0("https://abs.twimg.com/emoji/v2/72x72/", 
                            tolower(hex_runes), ".png"))

chat %>% 
  unnest(emoji) %>% 
  count(emoji, sort = TRUE) %>%
  head() %>% 
  left_join(emojis, by = "emoji") %>% 
  ggplot(aes(x = reorder(name, n), y = n)) +
  geom_col(width = 0.2) +
  geom_image(aes(image = emoji_url)) +
  ylab("") + xlab("") +
  ggtitle("Most often used emojis") +
  coord_flip() +
  theme_bw()

Thanks a lot Johannes, I will try it out.

Best wishes, Giuseppe
