如何更改此 R 图中的字体系列？

Question

我正在尝试将轴和图例的字体更改为衬线，但添加 family='serif' 对图例不起作用。我应该怎么做？

plot(sort(n.cdf),pch=3,cex = 0.5,xlab="Order",ylab="Cn",family="serif")
par(new=TRUE)
plot(sort(emp.c),col="red",pch=1,cex = 0.5,ann=FALSE, axes=FALSE)
par(new=TRUE)
legend( "topleft"
         , inset = c(0,0.1) 
         , cex = 1
         , bty = "n"
         , legend = c("Simulated", "Empirical")
         , text.col = c("black", "red")
         , pt.bg = c("black", "red")
         , pch = c(3,1)
       , family=c("serif")
)

Answer 1

在调用 legend() 之前将 family 绘图参数设置为您想要的值。通过显式调用 par().

来执行此操作

这是一个例子：

x <- y <- 1:10
plot(x, y, type = "n")
text(x = 5, y = 5, labels = "foo", family = "serif")

## set the font family to "serif"
## saving defaults in `op`
op <- par(family = "serif")

## plot legend as usual
legend( ... )

## reset plotting parameters
par(op)
