Question

当我管理该守则时,我就认为该守则是有效的。

plot(c(0,1), c(0, 1), type = "n")
legend("topleft", legend = c("Model", "Data"),
           lwd = c(3, NA),
           pch = c(NA, 16),
           bty = "n", inset = 0.02,
           cex = 2)

as expected, I see this: Nice legend

However, when I wrap it in pdf("legendTest.pdf") ... dev.off(), the saved PDF has a line through the point.

“extra

我能否纠正这种情况,或者我是否需要以另一种方式拯救? 在澳门一米处,问题正在由人民抵抗力量使用Preview和Kook来看待。我下载了Adobe Reader,看看它做了些什么,然后,文字和文字材料消失,只剩下模型。

You can fix this by explicitly setting the line type (argument lty), like this:

plot(c(0,1), c(0, 1), type = "n")
legend("topleft", legend = c("Model", "Data"),
       lwd = c(3, NA),
       lty = c(1, 0), # 0=blank, 1=solid (default). See ?par for more.
       pch = c(NA, 16),
       bty = "n", inset = 0.02,
       cex = 2)

<代码>lwd论点的文件,载于?par。

lwd The line width, a positive number, defaulting to 1 . The interpretation is device-specific, and some devices do not implement line widths less than one.

Mac s default R graphical device must be one of those. (FWIW, with your code, my own Windows graphics device does show a line through the data point, just as in the pdf.)

无论如何,在控制这一具体细节方面,它认为使用<代码>lty比lwd普遍更安全。
