Issues with ggplotly

[jimmyliu1326]

Hello,

I am encountering the following error when trying to render plotly object (ggplotly(p)) from Rmarkdown:

Error in dev_fun(file = tempfile(), width = width %||% 640, height = height %||%  : 
  No font found in CairoFonts() for "Helvetica:style=Regular"
Calls: <Anonymous> ... bscols -> ggplotly -> ggplotly.ggplot -> gg2list -> dev_fun

Here's my Dockerfile:

FROM rhub/r-minimal:4.1

RUN apk update \
     && apk add --no-cache libcurl curl-dev cairo-dev libxt-dev

RUN installr -d \
    -a "fontconfig" \
    -t "zlib-dev gfortran fontconfig-dev" \
    data.table dplyr ggplot2 \
    knitr rmarkdown tidyr \
    tibble purrr BiocManager \
    circlize plotly RColorBrewer \
    stringr bit64 Cairo \
    scales jsonlite htmltools \
    fontawesome reactable crosstalk \
    ComplexHeatmap svglite

RUN wget https://github.com/jgm/pandoc/releases/download/2.13/pandoc-2.13-linux-amd64.tar.gz && \
    tar xzf pandoc-2.13-linux-amd64.tar.gz && \
    mv pandoc-2.13/bin/* /usr/local/bin/ && \
    rm -rf pandoc-2.13*

Any help would be much appreciated!

Edit: I should add that Rmarkdown renders perfectly with ggplot objects, but fails when using ggplotly()

You need to install fonts

[gaborcsardi]

https://wiki.alpinelinux.org/wiki/Fonts says that this should be probably enough:

apk add terminus-font ttf-inconsolata ttf-dejavu font-bitstream-* font-noto font-noto-cjk ttf-font-awesome font-noto-extra

font-bitstream-* does not work, IDK if it should. But I get:

bash-5.1# fc-match "Helvetica:style=Regular"
NotoSans-Regular.ttf: "Noto Sans" "Regular"

You probably don't need all those font packages, btw.

Alternatively, you could also try this, but check the license of the MS fonts first: https://unix.stackexchange.com/a/438269/22660 This gives me:

apk --no-cache add msttcorefonts-installer fontconfig &&     update-ms-fonts &&     fc-cache -f
bash-5.1# fc-match "Helvetica:style=Regular"
Arial.ttf: "Arial" "Regular"
