以下代码将在PDF
文件
library(ggplot2)
ggplot(data=mtcars, aes(x=cyl, y=hp))+
geom_point() +
ggsave(filename="test1.pdf")
只有极少数字符,但只要它们不是曲线,它们就是脆弱的。 我想保留外表。
$ pdffonts test1.pdf

从https://tex.stackexchange.com/questions/27327/how-to-convert-text-in-a-pdf-file-from-fonts-text-to-outlines复制:我调用了此脚本pdfsquash
#!/bin/sh
if [ "x$1" = "x" -o "x$2" = "x" ]; then
echo Usage: `basename "$0"` "<input.pdf>" "<output.pdf>" >&2
exit 1
fi
gs -sDEVICE=pswrite -dNOCACHE -sOutputFile=- -q \
-dbatch -dNOPAUSE -dQUIET "$1" -c quit | ps2pdf - "$2"
我运行了你的代码,然后(在R之外,虽然你也可以使用system()
):
pdfsquash test1.pdf test1S.pdf
原文:
pdffonts test1.pdf
name type emb sub uni object ID
------------------------------------ ----------------- --- --- --- ---------
ZapfDingbats Type 1 no no no 10 0
Helvetica Type 1 no no no 11 0
新:
pdffonts test1S.pdf
