R-Change plot glyphs, embed fonts in PDF

Two problems with the recent use of R drawing

1. Use a different font

2. Save plot to PDF when font is embedded in PDF (embed the font)

These two problems can be solved by using Extrafont and Ghostscript.

1. Ghostscript

Installation: http://www.ghostscript.com/download/gsdnld.html

2. Extrafont (R package)

The following commands are executed in R

-Installation

> install.packages ("Extrafont") > Library (extrafont)      > #这一步定位系统字体. C:\windows\fonts\*.ttf, for example, takes a few minutes > Font_import () > Loadfonts ()

-Using

> #查看可用的font family> fonts ()

> Library (GGPLOT2) > #使用字体Times New Roman drawing > P <-ggplot (Mtcars, AES (X=WT, Y=mpg)) + geom_point () +  Xlab ("W Eight ") + Ylab (" Miles per gallon ") +  Theme (Text=element_text (family=" Times New Roman ") > #保存pdf > Ggsave (" Font _ggplot.pdf ", plot=p)

-Embed fonts into PDF

> #指定ghostscript的路径 > sys.setenv (r_gscmd = "C:/Program Files/gs/gs9.05/bin/gswin32c.exe") > #嵌入字体 > Embed_ Fonts ("Font_ggplot.pdf", outfile= "Font_ggplot_embed.pdf")

The font_ggplot_embed.pdf you get is the PDF you need!

Ability to see if a font is embedded by using Fonts, Properties, Adobe Reader, File-

Bonus: Embed fonts directly into PDF using Ghostscript command line

(Execute in cmd, don't forget to add ghostscript environment variable)
