使用ggplot2绘制Devanagari字体

Question

这里是一个可重复的例子

library(ggplot2)
library(showtext)

## Sahitya font for Devanagari characters

font_add_google("Sahitya")
showtext_auto()


p = ggplot(NULL, aes(x = 1, y = 1)) + ylim(0.8, 1.2) +
  theme(axis.title = element_blank(), axis.ticks = element_blank(),
        axis.text = element_blank()) +
  annotate("text", 1, 0.9, family = "Sahitya", size = 15,
           label = "मित्र ") 

print(p)

实际渲染应该是मित्र (意思是朋友)

推特帮助得到了答案。#Rstats社区是最好的。以下是细节

此外，请参阅ragg软件包

解决方案

library(ggplot2)
library(ragg)

file <- knitr::fig_path('.png')
agg_png(file)

ggplot(NULL, aes(x = 1, y = 1)) + ylim(0.8, 1.2) +
  theme(axis.title = element_blank(), axis.ticks = element_blank(),
        axis.text = element_blank()) +
  annotate("text", 1, 0.9, family = "Sahitya", size = 15,
           label = "मित्र ") 

invisible(dev.off())

不过，我注意到您必须先下载并添加字体。因此删除：

font_add_google("Sahitya")
showtext_auto()
