在不使用dev.off()的情况下将图形参数重置为默认值
在不使用dev.off()的情况下将图形参数重置为默认值
提问于 2012-02-15 19:32:59
比如页边距、方向等等。
dev.off()对我不起作用。我经常使用带有内置图形设备的RStudio。然后我有了绘图函数，我想要在默认的RStudio图形设备中绘图，或者如果我之前在一个新窗口中调用了X11()，我想要在新的窗口中绘图。
这种行为不适用于dev.off()。如果我的绘图函数总是调用dev.off()，它可能会无意中关闭X11()窗口，转而在RStudio设备中绘图。如果我总是先调用dev.off()，再调用X11()，即使我想在RStudio设备上绘图，它也总是会在一个新窗口中绘图。
通常，这可以用getOption("device")来解决，但是，它总是返回RStudioGD。

看到了吗?标准杆。这样做的想法是，将它们保存为找到它们时的原样，然后恢复：
old.par <- par(mar = c(0, 0, 0, 0))
## do plotting stuff with new settings现在将它们恢复为更改mar之前的状态：
par(old.par)Stack Overflow用户

在RStudio中，您只需导航到'Plots‘并选择'Remove plots’

一个包含所有默认值的简单函数就可以完成这项工作：

cex.axis = 1, cex.lab = 1, cex.main = 1.2, cex.sub = 1,
col = "black", col.axis = "black", col.lab = "black",
col.main = "black", col.sub = "black", crt = 0, err = 0L,
family = "", fg = "black", fig = c(0, 1, 0, 1),

ps = 12L, pty = "m", smo = 1, srt = 0, tck = NA_real_,

par(op)
}使用以下命令调用它：
reset_par()
