Question

当使用pdf（）时，我正努力在ggplot2中的绘图的轴标签上获得一个短划线。我正在使用MacOS High Sierra。

图表代码是：

fit1 <- lm(y ~ x, data.df)


 p1 <- ggplot(data.df, aes(x=x, y=y)) + 
  geom_point() +
  geom_abline(fit1, intercept = coef(fit1)[[1]], slope = coef(fit1) . 
 [[2]], color="red", size=.2) +
  xlab("CMP Left–Right Score")) +
  ylab("Disposition Towards BI")

如果我们这样做，这似乎正确呈现

quartz()
p1

但是，下面给出了一个连字符而不是一个短划线：

pdf(file="pooled.pdf", width=8, height=6)
p1
dev.off()

数据是：

Answer 1

开罗通常更善于处理字体，

library(ggplot2)

ggsave('en.pdf',ggplot() + xlab("hyphen-hyphen en–en em—em"),
       device = cairo_pdf)

在打印到pdf（）
