调整图例闪亮R

Question

我正试图摆脱空白的空白，如下所示，但是似乎无法弄清楚如何做到这一点。

示例代码：

 legend("bottom", 
         colnames(bvoip.collab.seats)[3:4],
         xpd = FALSE,
         horiz = TRUE, 
         #ncol = 1 , 
         inset = c(0, 0),
         bty = "o",
         bg = "gray90", 
         box.col="gray90",
         pch = c(15, 15, 15, 15, 15), 
         col = c(attDarkBlue,attOrange,attGreen), 
         legend = c(" Collaborate-Enhanced Mobile"," Collaborate"," Collaborate-Internal"),
         pt.cex = 1.3,cex = 0.8,yjust = 0.5)

Answer 1

这是一种解决方法，但是在Legend（）中使用“ text.width”属性可以完成工作。这不是完美的，但可以。

legend("bottom", 
         colnames(bvoip.collab.seats)[3:4],
         xpd = FALSE,
         horiz = TRUE, 
         text.width=c(.5,.2,.5),
         #ncol = 1 , 
         inset = c(0, 0),
         bty = "o",
         bg = "gray90", 
         box.col="gray90",
         pch = c(15, 15, 15, 15, 15), 
         col = c(attDarkBlue,attOrange,attGreen), 
         legend = c(" Collaborate-Enhanced Mobile", " Collaborate", " Collaborate-Internal"),
         pt.cex = 1.3,cex = 0.8,yjust = 0.5)
