在macos上的R绘图中使用texlive字体

tex-live fonts plot r

ivo Welch · 技术社区 · 6 年前

我以前让它工作,但现在不工作了。以下是我尝试将texlive 2018 bera字体提供给R:

$ R --no-init-file
> options(texlive= "~/Documents/texlive/2018/")
> options(texfonts= paste0(getOption("texlive"), "/texmf-dist/fonts/"))
>
> pdfFonts(Bera = Type1Font("Bera", paste0(getOption("texfonts"), "afm/public/bera/", c("fvsr8a","fvsb8a","fvsro8a","fvsbo8a"), ".afm")))
> options(pfbdir = c(paste0(getOption("texfonts"), "type1/public/bera/")))
> pdfFonts("Bera")
$Bera
$family
[1] "Bera"

$metrics
[1] "~/Documents/texlive/2018//texmf-dist/fonts/afm/public/bera/fvsr8a.afm"
[2] "~/Documents/texlive/2018//texmf-dist/fonts/afm/public/bera/fvsb8a.afm"
[3] "~/Documents/texlive/2018//texmf-dist/fonts/afm/public/bera/fvsro8a.afm"
[4] "~/Documents/texlive/2018//texmf-dist/fonts/afm/public/bera/fvsbo8a.afm"
[5] "Symbol.afm"

$encoding
[1] "default"

attr(,"class")
[1] "Type1Font"

> pdf(file="test.pdf")
> plot( 1 )
> dev.off()
null device

$ pdffonts test.pdf  ## from brew poppler

也许pfb字体也需要安装在macos本身上,这过去很简单(需要双击字体名称,但最新的macos似乎不再喜欢这种字体了。或者其他什么地方出了问题?

更新:我还尝试了showtext软件包(需要安装XQuartz)。同样的结果:

n <- "~/Documents/texlive/2018//texmf-dist/fonts/type1/public/bera/"
library( showtext )
font_add("Bera", paste0(n,"fvsr8a.pfb"), bold=paste0(n,"fvsb8a.pfb"),italic=paste0(n,"fvsro8a.pfb"),bolditalic=paste0(n,"fvsbo8a.pfb"))
showtext_auto()
pdf(file="t.pdf")
showtext_auto()
plot(1:20)
dev.off()

同样的结果---我的texlive bera(pfb)字体对PDF不可见。

一个指向一步一步文档的指针(如何处理和诊断问题)会很好。请帮忙。

我终于成功了。步骤:

https://tex.stackexchange.com/questions/457922/making-texlive-bera-font-accessible-on-macos-r-etc

brew tap homebrew/cask-fonts
brew install --cask font-bitstream-vera  # after 2021

brew search font- .

[2] 按照中的说明操作 https://cran.r-project.org/web/packages/extrafont/README.html

install.packages('extrafont')
library(extrafont)
font_import()
loadfonts()

[3] 使用它们

> pdf("test.pdf", family="Bitstream Vera Serif")
> plot(1:10)
> dev.off()

[4] 检查test.pdf文件是否使用字体(必须安装poppler):

pdffonts test.pdf
name                                 type              encoding         emb sub uni object ID

BitstreamVeraSerif-Roman             Type 1            Custom           no  no  no      11  0
