【r<-方案】如何修改画图使用的字体

这是画图时都会存在的一个困惑，今天我终于尝试搜索和解决。
默认，R分为两类作图系统，一类是base plot，另一类是非基础绘图系统，像grid，以及基于它的ggplot2等。
对于基础的绘图系统，我们可以在使用plot时设定family参数，即可修改绘图字体。
例子：
> x = seq(1,10,1)
> y = 1.5*x
> windowsFonts(A = windowsFont("Times New Roman"))
> plot(x, y,
+ family="A",
+ main = "title",
+ font=2)
base plot
对于ggplot2，我们需要设定主题theme。
例子：
> windowsFonts(Times=windowsFont("Times New Roman"))
> library(ggplot2)
> ggplot(mtcars, aes(x=wt, y=mpg)) + geom_point() +
+ ggtitle("Fuel Efficiency of 32 Cars") +
+ xlab("Weight (x1000 lb)") + ylab("Miles per Gallon") +
+ theme_bw() +
+ theme(text=element_text(family="Times", face="bold", size=12)) #Times New Roman, 12pt, Bold
ggplot2
如果你仔细看了上面的代码，你会发现上面两种设定解决方案都是一致的，只不过不同的绘图系统设置方式不同，它们都通过windowsFonts()实现。
从函数名就可以看出，它不能适用于其他系统，比如linux
> windowsFonts(Times=windowsFont("Times New Roman"))
Error in windowsFonts(Times = windowsFont("Times New Roman")) :
could not find function "windowsFonts"
extrafont包
extrafont package 提供了更多的特性，它的操作更为普适，而且它可以导入系统中的字体库！这样我们在绘图时有了更多的选择。
安装：
p_load(extrafont)
# or
install.packages("extrafont", dependencies=TRUE)
library(extrafont)
推荐使用
pacman包管理包，它可以让代码更简洁，可以更简洁从CRAN，Github，以及bioconductor下载、安装以及加载包等，见【r<-包】管理你的R包——pacman包介绍
然后导入字体
> font_import()
Importing fonts may take a few minutes, depending on the number of fonts and the speed of the system.

画图使用字体：
> ggplot(mtcars, aes(x=wt, y=mpg)) + geom_point() +
+ ggtitle("Fuel Efficiency of 32 Cars") +
+ xlab("Weight (x1000 lb)") + ylab("Miles per Gallon") +
+ theme_bw() +
+ theme(text=element_text(family="YouYuan", face="bold", size=12))
Youyuan字体
记住，每次注册字体库都只能在当前线程中使用，如果重启R线程需要重新载入，就是再运行一次loadfonts(device="win")。
另外非windows系统设定device="win"是没用的，默认不用设定参数即可。
