What does this error imply ?
When are you getting this error? If it is in the middle of a script can you supply us with the code.
Copy the code and paste it here between
```
```
This gives us formatted code that we can copy, paste and run
Also can you give us the output from
sessionInfo()
Again the best way to supply it is to copy and paste between
```
```

Your code in running with no errors for me. However I am running Ubuntu Linux not windows.
Doing an internet search pulled up the information ( below code segment). Are you making a call somewhere for a specific font?

AI Overview
The warning message "Warning in grid.Call.graphics(C_text, as.graphicsAnnot(x$label), x$x, x$y, : font family not found in Windows font database" indicates that R, specifically when using packages like ggplot2 or grid for plotting, is unable to locate a specified font family within the Windows font database.
This typically occurs in the following scenarios:
Missing Font:
The font family specified in your R code (e.g., in theme() settings in ggplot2) is not installed on your Windows system.
Rendering Engine Limitations:
When rendering R Markdown or Quarto documents, the default rendering engine might not have direct access to all system fonts.
To resolve this issue, consider the following:
Install the Missing Font: Ensure the font family you are trying to use is installed on your Windows system. You can typically do this by downloading the font file (e.g., .ttf or .otf) and installing it.
Use a Different Rendering Engine (for R Markdown/Quarto):
Install the ragg package:
Code
install.packages("ragg")
Set ragg_png as the device for rendering plots in your R Markdown or Quarto document by adding the following line at the top of your file:
Code
knitr::opts_chunk$set(dev = "ragg_png")
The ragg package provides a more robust graphics device that can often access system fonts more reliably during rendering.
