保存到文件后，情节被切断了

Question

我的无花果在情节之外有一个很大的传说。 6条长描述的线条当我保存它时，图例不会显示。我调整了标准杆，但它仍然不起作用。

legend("topright", inset=c(-0.6,0),xpd=TRUE,cex=0.8,
+legend=c("A_all peaks","B_ from all peaks","C_from all peaks","A_from unique peaks",
+"B_from unique peaks","C_from unique peaks",
+"A_from overlap peaks","B_from overlap peaks","C_from overlap peaks"),
+col=c("green","red","blue","lightgreen","pink","lightblue","darkgreen","darkred","steelblue"),
+pch=c(20,20,20,20,20,20,20,20,20),bty="n")

> par()$oma
[1] 2 2 2 2 
> par()$mar
[1] 5.1 4.1 4.1 8.0

当保存宽度较长（尝试800,1000像素）时，没有传说显示。但是，当短宽度（）时，部分传奇显示。这真的让我很困惑。第一张图是500 * 333，第二张图是500 * 800。

Answer 1

不确定你是如何将剧情保存到文件中的，但我通常的惯例是通过常规手段在R中制作漂亮的情节：

plot(blah,blah,blah)
legend(blah,blah,blah)

然后，一旦我对R控制台图形的外观感到满意，我会使用pdf()或其中一个表兄（jpeg()，tiff()等）来保存它要归档，确保设置宽度和高度参数如下：

# set up plotting device
pdf( {{FileName}}, 
   width = par('din')[1],
   height = par('din')[2])

plot(blah,blah,blah)
legend(blah,blah,blah)

# disconnect the plotting device
dev.off()

Answer 2

使用png()或tiff()保存它：

tiff("filename",

<code for plot>,
height=5,width=7)
dev.off()

Answer 3

绘图后，尝试

% your code…

dev.copy(pdf, 'yourfile.pdf')
dev.off()
