这应该很简单，但我不知道如何从我的图例中删除边框。我还想将图例放在图表中并删除内部网格线以及顶部和左侧边框。我正在使用 scatterplot 函数，这是我迄今为止编写的代码：

scatterplot(Comp1~ln1wr|Season, moose,  
      xlab = "Risk", ylab = "Principal component 1",
      labels= row.names(moose), by.groups=T, smooth=F, boxplots=F, legend.plot=F)
      legend("bottomleft", moose, fill=0)

在这里，我只是在尝试是否可以将图例放置在其他位置，但是每次运行此代码时，都会出现错误

Error in as.graphicsAnnot(legend) : 
  argument "legend" is missing, with no default

我想将图例放在图表中，但不会与数据显示冲突。这是样本数据：

structure(list(ID = structure(c(1L, 1L, 1L, 1L, 1L, 32L, 33L, 
33L, 34L, 34L, 34L), .Label = c("F07001", "F07002", "F07003",

我会建议

par(bty="l",las=1)
scatterplot(Comp1~ln1wr|Season, moose,  
      xlab = "Risk", ylab = "Principal component 1",
            labels= row.names(moose),
            by.groups=TRUE, smooth=FALSE, boxplots=FALSE,
            grid=FALSE,
            legend.plot=FALSE)
legend("bottomright", title="Season",
       legend=levels(moose$Season), bty="n",
       pch=1:2, col=1:2)
  • 如 中所示?legend，bty控制图例框——"n"表示“无。
  • 我将图例放在右下角而不是左下角，因为这样似乎可以更好地避免您的数据。
  • 我曾经bty="l"消除顶部和右侧的盒子边缘（这意味着“盒子类型L”）
  • 我曾经las=1让 y 轴刻度标签水平 - 你没有要求，但我非常喜欢它
  • grid=FALSE删除内部网格线

您必须唯一的驼鹿 ID，因为每只驼鹿有多个点。

传奇（“左下角”，传奇=独特（驼鹿））

然后你必须将颜色和点类型与你的图例相关联（对应于你情节中的驼鹿 ID）。我也会看看 plot() 而不是 scatterplot()。
