在基本R圖中結合圖例和粘貼命令

Question

我想將一些文本paste()到圖例中的圖例中，但是我無法讓R正確讀取c()和paste()命令。

plot(1:10,1:10,type="n")

a <- 23
b <- 32

legend("topleft",inset=0.05,
       legend=c("1-15: n=[23]\nEstimated","15+: n=[32]\nAveraged"),
       lty=c(1,1),col=c("black","red"),bty="n",cex=1.5)

legend("topright",inset=0.05,
       legend=c(paste("1-15: n=[",a,"]\nEstimated","15+: n=[32]\nAveraged")),
       lty=c(1,1),col=c("black","red"),bty="n",cex=1.5)

因此，左側的圖例是手動創建的，我想要的輸出是在右側創建相同的圖例。

Answer 1

你近了 我相信這就是您想要的：

plot(1:10, 1:10, type="n")
a <- 23
b <- 32

legend("topright", inset = 0.05,
       legend = c(paste("1-15: n=[", a, "]\nEstimated"),
                  paste(" 15+: n=[", b, "]\nAveraged")),
       lty = c(1,1),
       col = c("black","red"), bty = "n", cex = 1.5)
