QUESTION
I am trying to include emojis in a plot created with R and ggplot2. I´m currently using the emoGG package, specifically the geom_emoji()
function. The weird thing is that I can pass the emoji name as a character string but I cannot assign the character string to a variable and use that instead. This makes it impossible to automate the assignment with a lookup table. Here is an example of what I mean:

Answered 2019-Nov-22 at 14:48I don't think the developer anticipated this use. The relevant section of their code here on Github assumes that you're passing a named parameter with a string literal all the time.
This code below will work for your use. But I don't think you can easily plot multiple emojis on a single plot using aesthetics as you would for other ggplot2
based extensions. There may be other packages that plot symbols that might fit your needs.
