Unidentified Emojis

[mapale1]

Many of the emojis are not identified, for example, <U + 0001F913> <U + 0001F914> <U + 0001F644>

Thanks for reporting. However, I can't reproduce your issue. Assuming the emojis below are the one you're having problems with, they parse without a problem.

x <- c(
  "05/11/2019, 08:52 - Johannes Gruber: Is there a problem with this emoji?",
  "05/11/2019, 08:52 - Johannes Gruber: 🤓",
  "05/11/2019, 09:00 - Johannes Gruber: 🤔",
  "05/11/2019, 09:00 - Johannes Gruber: 🙄"
)

library(tidyr)
library(dplyr)

rwhatsapp::rwa_read(x) %>% 
  unnest(c(emoji, emoji_name)) %>% 
  left_join(rwhatsapp::emojis, by = "emoji")
#> # A tibble: 3 x 8
#>   time                author  text  source emoji emoji_name name  hex_runes
#>   <dttm>              <fct>   <chr> <chr>  <chr> <chr>      <chr> <chr>    
#> 1 2019-11-05 08:52:49 Johann… 🤓    text … 🤓    nerd face  nerd… 1F913    
#> 2 2019-11-05 09:00:49 Johann… 🤔    text … 🤔    thinking … thin… 1F914    
#> 3 2019-11-05 09:00:49 Johann… 🙄    text … 🙄    face with… face… 1F644

Maybe you can share an excerpt of your chat log with which you have the problems? I'm matching emojis against a data.frame of known emojis. So it is prone to error theoretically as I couldn't find the exact Unicode characters Whatsapp is using.

many time i tried to work this project for my data but i cant get it on succesfull. how can i use this code blog. thanks for regards

Please give a more detailed description of what you are trying to do and what isn't working for you. Ideally provide a reproducible example of what exactly is causing an error for you (e.g., with this) .

Interestingly I seem to have a similar problem, but there are differences between the output in an Rmarkdown, ggplot and console output...
Rmarkdown:

Console:

GGplot:

Hi @pintodossantos.This is an issue with the font ggplot2 is using by default, not with rwhatsapp, which seems to do fine here. Are you using a Mac? I outlined a solution here.

[pintodossantos]

Thanks! I understand the ggplot part, but the Rmarkdown?

[JBGruber]

Okay, now I get it. I don't really know a lot about how RStudio is displaying RMarkdown code chunks. I tried this on my machine and it works fine. On rstudio.cloud I get the same result as you. In both cases, the output looks fine when rendered to html. I guess this is another font or encoding issue. But the issue is only displaying the emojis. The data itself is correct.

What operating system do you use? And do you have the newest version of RStudio?

I don't think this issue has anything to do with rwhatsapp. Rather it is a problem with the printing method in RStudio on some systems.

If you explicitly call a different printing method it should work for tables as well. For example something like:

emojis <- rwhatsapp::rwa_read(x) %>% 
  unnest(c(emoji, emoji_name)) %>% 
  left_join(rwhatsapp::emojis, by = "emoji")

emojis %>% 
  knitr::kable()

or:

emojis %>% 
  DT::datatable()
