Chinese characters in R plots can't display properly. about shiny

[taiyodayo]

ah I see what you meant.
I was only trying to help the original poster and did not mean to say this as a feature request.
please accept my apologies.

I do add local fonts in my Dockerfile.

[taiyodayo]

enable sudo command by invoking rocker/rstudio like this:

docker run  -e ROOT=TRUE -e PASSWORD=yourpassword --rm -p 8787:8787 rocker/tidyverse

in RStudio, open terminal and run

sudo apt update && sudo apt install fonts-noto-cjk

this will install Noto font set for CJK environment.

Once you do, simply set default typeface for the display device by calling from R,

par(family="Noto Sans")

Now it should be able to display any CJK characters in plots, like "**語とか日本語とか"!

This should work for pretty much all languages, as Noto is a font project aiming to cover every language on Earth. Just install the appropriate apt package for the desired language. ("fonts-noto-core" should cover nealy all languages)

(Filed in the wrong repo, suggest to move to rocker/shiny)

above solution is not limited to just shiny, but all rocker images that use ggplot etc. I feel this is the correct repo :)

It's not, and as we something try to explain gently, there are thousands of packages on CRAN, and tens of thousands of other packages on the distribution repositories. We cannot possibly cater to all possible sub-specialisations. I understand that not having the local font is frustrating, but even if we add it for you it is still missing for a number of other languages. So best maybe to consider a derived container or a locallly modified one.

I think this problem has been solved, so I will close it.
