Question

...指定“topright”＆amp;将符号放在图例的右侧而不是标签的左侧。

基本上我希望我的传奇位于我的情节右上角的一个方框中，并且我的所有文字都是右对齐的，而不是左对齐。

我的代码处于循环中并应用于100多个图形，因此我试图将图例保留在每个图形的相同位置。

我尝试使用just和adj这对我不起作用。

legend("topright", legend=c("data", "data", "data", "data", "data",
                "data", "data", "data", "data", "data", "data"),
        ncol = 1,
        lty = c(1, NA, NA, NA, NA, 1, 1, 1, 2, 2, 2), 
        pch = c(NA, sym[1], sym[2], sym[2], sym[3], 19, 17, 15, 19, 17, 15), 
        col = c(blue, aa, aa, aa, aa, gr, bl, pu, gr, bl, pu),
        pt.bg = c(NA, a, b, c, d, NA, NA, NA, NA, NA, NA), 
        pt.cex = c(NA, 1, 1, 1, 1, .5, .5, .5, .5, .5, .5),
        cex = .75, 
        lwd = c(2, NA, NA, NA, NA, 1, 1, 1, 1, 1, 1),
        text.col = "black")

## right-justifying a set of labels: thanks to Uwe Ligges
x <- 1:5; y1 <- 1/x; y2 <- 2/x
plot(rep(x, 2), c(y1, y2), type = "n", xlab = "x", ylab = "y")
lines(x, y1); lines(x, y2, lty = 2)
temp <- legend("topright", legend = c(" ", " "),
               text.width = strwidth("1,000,000"),
               lty = 1:2, xjust = 1, yjust = 1,
               title = "Line Types")
text(temp$rect$left + temp$rect$w, temp$text$y,
     c("1,000", "1,000,000"), pos = 2)
