use with RMarkdown

[McCartneyAC]

Hi, I got a great ggplot2 image to render with Emoji marking the nodes of a network with ggraph. I'm really pleased with it and want to publish up my process with RMarkdown, however, when I get to the first chunk of code with emojifont, it pulls this error:

---

Quitting from lines 85-89 (fish_pond.Rmd) Error in grid.Call.graphics(C_text, as.graphicsAnnot(x$label), x$x, x$y, : invalid input '🐬' in 'utf8towcs' Calls: ... drawDetails -> drawDetails.text -> grid.Call.graphics In addition: There were 13 warnings (use warnings() to see them)

Execution halted

---

I made sure that the .rmd file was encoding in UTF8, but nevertheless the message persisted. When I removed that line of code, the same error recurred when the emojifont package was next utilized.

Any suggestions?

Thanks!

Andrew

If you want to use it in rmd, pls follow example on https://raw.githubusercontent.com/GuangchuangYu/emojifont/master/vignettes/emojifont.Rmd and use {r fig.showtext=TRUE}
