Question

我必须将情节中的所有文本加粗。

我正在使用以下方法绘制密度：

par(mfrow=c(1,1),family="serif")

plot(density(rxyTop30),col="green",lty=1,lwd=3,bty="l",main="",
xlab=expression(paste(R[xy])),xlim=c(0.0,0.5),ylim=c(0,12),font=2)
 lines(density(jfTop30),col="blue",lty=1,lwd=3)
  legend("topright",c(expression(paste(R[xy]," with 30 ancestors with most 
  progeny"),paste(beta," (",alpha," = 0.96",", ",beta, " = 8.031)"))),
  lwd=c(3,3),lty=c(1,1),col=c("green","blue"),bty="n")

我尝试在代码中的不同位置插入font=2。它只会使刻度线在每个轴上都加粗。

Answer 1

a <- 2
b <- 5
plot(a,b)
legend("topleft", legend = c(as.expression(bquote(bold("Bold"))),
                             as.expression(bquote("Not Bold"))))

result

Answer 2

参数 font 控制刻度数的状态。如果您希望轴标签为粗体，则需要参数 font.lab=2。即，以下代码...

plot(density(rxyTop30),col="green",lty=1,lwd=3,font.lab=2,bty="l",main="",
xlab=expression(paste(R[xy])),xlim=c(0.0,0.5),ylim=c(0,12),font=2)
 lines(density(jfTop30),col="blue",lty=1,lwd=3)
  legend("topright",c(expression(paste(R[xy]," with 30 ancestors with most 
  progeny"),paste(beta," (",alpha," = 0.96",", ",beta, " = 8.031)"))),
  lwd=c(3,3),lty=c(1,1),col=c("green","blue"),bty="n")

R：使图例中的文字和图中的xlab＆ylab参数变为粗体？
