将图标保存为PDF后，图例变得杂乱无章

Question

我已经绘制了几个折线图。 但将我的工作保存到pdf文件后。传奇线运行> <整个图变得凌乱~~ 我可以知道任何方法来调整它吗？

输出类似于下面

如该图所示，图例凌乱。我可以知道可以做些什么来确保线路不会运行？

我已经绘制了几个线图。但在将我的工作保存到pdf文件后。图例线条运行> <整个图形变得凌乱

这似乎是说，您在R图形窗口上的原始输出是好的。如果您想将绘图保存为pdf文件，请先不要在R图形窗口上生成它，然后保存它。您应该立即将它绘制在pdf文件上。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在您的工作目录下。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Microsoft Word的工作，那么你可以改为试试这个：

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! 

这将输出你的情节为JPEG。您可以将其插入WORD，然后将其转换为PDF。你不应该再这样问题了。
