r - plot.xts 对象---如何使图例字体更粗？

Question

我有以下有效的代码。我想让图例字体更粗，但我现在正在使用自动图例，只是想知道是否可以这样做？提前谢谢了！

plot.xts(Margins, 
         screens = c(1,1,2,2,3,3,4,4),
         col = brewer.pal(n=9,"PuBu")[c(8,4,6,9)], lwd = 6,
         legend.loc = c("topright"), auto.legend = T,
         main="Margin Comparison")

Answer 1

只是font=2用作论据。

plot.xts(Margins, 
         screens = c(1,1,2,2,3,3,4,4),
         col = brewer.pal(n=9,"PuBu")[c(8,4,6,9)], lwd = 6,
         legend.loc = c("topright"), auto.legend = T,
         main="Margin Comparison",
         font = 2
)
