带一个条的R条形图-如何正确绘制 [英] R Barplot with one bar - how to plot correctly

问题描述

我想在R中绘制常规条形图，但只有一个条形图.我不喜欢这样的事实，即条形宽度变为整个图的宽度.我希望酒吧变得更稀薄"，但我不知道该怎么做.

I want to plot a regular bar plot in R, but with just one bar. What I don't like is the fact that the bar width gets to be the width of the whole plot. I want the bar to be "thinner", but I don't know how to do it.

默认命令是:

barplot(percentage, col=c("brown4")) 

其中百分比是分数.我尝试使用xlim参数，但它变得非常混乱(条形图完全移至右侧或左侧).例如，我尝试过:

where percentage is a fraction. I tried using xlim parameter, but it gets very messy (bar goes completely to the right or left). For example, I tried:

barplot(percentage, col=c("brown4"), xlim=c(0.5,1))

但是，这会进一步扩大标准.我是R菜鸟.

but this stretches the bar even more. I am an R noob.

推荐答案

您可以尝试使用要绘制的设备的宽度.例如:

You may try to play around with the width of the device you plotting to. E.g.:

# plot to a Windows graphic device
windows(height = 10, width = 4)
barplot(0.5)

# plot to PDF
pdf(height = 10, width = 2)
barplot(0.5)
dev.off()

您也可以将width与xlim

barplot(0.5, width = 0.1, xlim = c(0, 1))
