在不使用dev.off()的情况下将图形参数重置为默认值

Question

如利润,方向等......

dev.off()不适合我.我经常使用RStudio,内置图形设备.然后我有绘图功能,我想要在默认的RStudio图形设备中绘制,或者如果我X11()在新窗口中调用之前绘制.

此行为不起作用dev.off().如果我的绘图功能总是调用dev.off(),它可能会无意中关闭X11()窗口,而是在RStudio设备中绘图.如果我总是打电话dev.off()跟随X11(),它将始终在新窗口中绘图,即使我想在RStudio设备中绘图.

getOption("device")然而,通常可以通过总是返回来解决RStudioGD.

Answer 1

见？par.这个想法是你在找到它们时保存它们,然后恢复:

old.par <- par(mar = c(0, 0, 0, 0))
## do plotting stuff with new settings

现在恢复之前我们改变了mar:

par(old.par)

Answer 2

在RStudio中,您可以导航到"Plots"并选择"Remove plots"

Answer 3

如果您在启动时已经错过了保存默认参数,并且您不想重新启动会话,则可以打开终端并通过(通常)键入R运行R.

然后输入:

帕()

它将打印所有默认值.

您可以将它们保存在文本文件中,然后导入到当前工作的工作区中.

Answer 4

一个包含所有默认值的简单函数可以完成这项工作:

  reset_par <- function(){
    op <- structure(list(xlog = FALSE, ylog = FALSE, adj = 0.5, ann = TRUE,
                         ask = FALSE, bg = "transparent", bty = "o", cex = 1, cex.axis = 1,

    par(op)
  }

用它来称呼它:

reset_par()

Answer 5

规范的答案仅在评论中（由 Cookie 提供），并且很容易被忽视：

获取当前/默认参数

old.par <- par(no.readonly = TRUE)

在您的代码中设置它们，例如

par(mai=c(0,0,0,0))

然后你可以用以下命令重置参数

par(old.par)

或者，在一个函数中

on.exit(par(old.par))

Answer 6

对于边距，?par 提供默认值 c(5,4,4,2)+0.1。以下应将边距重置为默认值。

par(mar=c(5,4,4,2)+0.1)
