将图块保存为PDF后，传奇变得混乱

Question

我绘制了几个折线图。 但在将我的工作保存到pdf文件后。图例线运行＆gt;＆lt;整个图变得凌乱~~ 我可以知道任何调整方法吗？

输出类似于以下

如图所示，传说凌乱。我可以知道如何确保线路不运行吗？

这似乎说你在R图形窗口上的原始输出很好。如果要将绘图保存为pdf文件，请不要先在R图形窗口中生成它，然后保存。你应该立即在pdf文件上绘制它。使用以下内容：

pdf("myplot.pdf")  ## open a pdf file for plotting
## ... your R code for plotting
dev.off()  ## close pdf; you must do this!

输出pdf位于您的工作目录下。如果您不知道，请在R中执行getwd()，您将看到此路径。

如果您使用的是Microsoft Word，那么您可以尝试使用它：

jpeg("myplot.jpeg", quality = 100)  ## open a JPEG file for plotting; no quality loss
## ... your R code for plotting
dev.off()  ## close JPEG; you must do this!

这会将您的绘图输出为JPEG。您可以将其插入WORD，然后将其转换为pdf。你不应该再这样有问题了。
