I'm struggling with a persistent issue while trying to embed the Ubuntu Condensed font in ggplot2 plots in R Markdown PDF outputs.

I've installed both Ubuntu and Ubuntu Condensed fonts for all users on my Windows machine
I've verified both fonts are listed under systemfonts::system_fonts() and extrafont::fonttable()
I've registered both fonts with Windows bitmap devices
I'm using AGG as the backend graphics device
Within RStudio's viewer pane, the plot is displayed properly with both fonts working:

When generating a PDF from an R Markdown document Ubuntu works fine, but Ubuntu Condensed completely fails to embed:

I managed to get it working with showtext but I would like to avoid using showtext if possible

Here's my current setup:

knitr::opts_chunk$set(
  dev = "cairo_pdf",
    echo = FALSE,
    message = FALSE,
    warning = FALSE
)

library(ggplot2)
library(ggtext)
library(extrafont)
library(systemfonts)

loadfonts()

grDevices::windowsFont("Ubuntu")
grDevices::windowsFont("Ubuntu Condensed")

ggplot(mtcars, aes(x=wt, y=mpg)) + 
  geom_point() +
  labs(title = "This is Ubuntu", x = "This should be Ubuntu Condensed", 
       y = "This should be Ubuntu Condensed") +
  theme(plot.title=element_textbox_simple(family="Ubuntu"),
        axis.title = element_text(family = "Ubuntu Condensed"),
        axis.text = element_text(family = "Ubuntu Condensed"))

And here's my session info:

Use dev = "ragg_png" and make sure, your fonts are properly registered by running font_families(). May I ask, why you want to avoid showtext? It's a great package! – dog Commented yesterday
Thanks for taking the time to reply! ragg_png does work indeed, but I prefer a vector graphics solution. I'm using showtext_auto provisionally—it is a great package, but it doesn't fit into the company workflow. So what puzzles me is that with my original workflow Ubuntu (regular) works fine, and Ubuntu Condensed used to work in previous R versions. I just tested it in R 4.0.0, and it worked perfectly, so I'm trying to figure out what exactly changed in recent versions. – Kateřina Hudáčová Commented 22 hours ago

I downloaded the two Ubuntu fonts here. Double click both files and then click "Install" to register them properly on windows.

With registered fonts

Instead of manually, you can also register fonts with

font_files <- list.files("/path/to/your/fonts", pattern = "\\.ttf$", full.names = TRUE)

for (file in font_files) {
  font_name <- tools::file_path_sans_ext(basename(file))  # Extract font name from file name
  register_font(name = font_name, plain = file)  # Register each font
}

But always make sure, that the fonts are listed in font_families().

Be sure, to run your ggplot in a chunk that is NOT setup. Also set dev to "ragg_png" which is a great hint I found here.

The viewport when put to AGG displays both fonts the same as the PDF:

Code

---
title: "Font Embedding Example with dev = 'ragg_png' and registered Fonts"
output:
  pdf_document: default
  html_document:
    df_print: paged
---

```{r setup, echo=F, warning=F}
knitr::opts_chunk$set(
  dev = "ragg_png", 
  echo = FALSE,
  message = FALSE,
  warning = FALSE,
  dpi = 400
)

```    

```{r extraFont, echo=F, warning=F}
library(ggplot2); library(ggtext)

ggplot(mtcars, aes(x=wt, y=mpg)) + 
  geom_point() +
  labs(title = "This is Ubuntu", x = "This should be Ubuntu Condensed", 
       y = "This should be Ubuntu Condensed") +
  theme(plot.title=element_textbox_simple(family="Ubuntu"),
        axis.title = element_text(family = "Ubuntu Condensed"),
        axis.text = element_text(family = "Ubuntu Condensed"))
```

With showtext_auto

Another way is using showtext_auto()

Code

---
title: "Font Embedding Example"
output: 
  pdf_document
---

```{r showtext, echo=F, warning=F}

library(showtext);library(ggplot2);library(ggtext)
    
font_add("Ubuntu", regular = "Ubuntu-Regular.ttf")
font_add("Ubuntu Condensed", regular = "UbuntuCondensed-Regular.ttf")

# Enable showtext for this specific plot only
showtext_auto()

ggplot(mtcars, aes(x=wt, y=mpg)) + 
  geom_point() +
  labs(title = "This is Ubuntu", x = "This should be Ubuntu Condensed", 
       y = "This should be Ubuntu Condensed") +
  theme(plot.title=element_textbox_simple(family="Ubuntu"),
        axis.title = element_text(family = "Ubuntu Condensed"),
        axis.text = element_text(family = "Ubuntu Condensed"))

showtext_auto(FALSE)
```
