When running this code from an r markdown file:
---
output: pdf_document
---
```{r test}
library(extrafont)
library(waffle)
parts <- c(80, 30, 20, 10)
waffle(parts, rows=8, use_glyph="shield")
```
I'm getting the following warnings that look something like:
## Warning: Removed 4 rows containing missing values (geom_text).
## Warning in grid.Call.graphics(C_text, as.graphicsAnnot(x$label), x$x, x
## $y, : conversion failure on 'ï„2' in 'mbcsToSbcs': dot substituted for <ef>
## Warning in grid.Call.graphics(C_text, as.graphicsAnnot(x$label), x$x, x
## $y, : conversion failure on 'ï„2' in 'mbcsToSbcs': dot substituted for <84>
I've tried several things such as:
- using the latex fontawesome package.
- running the example here: Compile RMarkdown PDF with Waffle Chart and Glyphs FAILURE. MWE included (I had issues with quartz_pdf, perhaps become I'm on Windows?)
- using the fontawesome, emojifont, and emo r packages
Note that the glyphs are properly rendered when outputing an HTML file. They are also correctly rendered when just calling the waffle code in the console.
I can even render fontawesome symbols directly through the latex fontawesome package by typing something such as \faAmazon
I've sunken most of today in trying to figure this out (100% sunken cost fallacy at this point).
Edit: Just FYI incase anyone else runs into this. I rendered the chart as a .png, as a temporary file and called the image back. Still looking for the proper way to do this as I would assume I'm losing some image quality along the way.
