r - 如何控制条之间的空间？

Question

我正在使用以下代码绘制条形图:

heights1=c(5,5,4.5,4)
barplot(heights1, main="Language ", names.arg=c("Hindi R/W", "Speak" , "English 
R/W","Speak"), ylab=" level ", xlab="Language starting with mostly used",  
cex.names=0.8, col=c("darkblue","red"))

输出如下:

但是我想要的是“印地语读/写”和“说”应该组合 而没有任何间隙，然后出现一个空格，然后“英文读/写”和“说”应该组合。我该怎么做呢？

Answer 1

您应该在space=函数中添加参数barplot()，其中数字对应于每个小节前的空格。

heights1=c(5,5,4.5,4)    
barplot(heights1, main="Language ", names.arg=c("Hindi R/W", "Speak" , "English 
  R/W","Speak"), ylab=" level ", xlab="Language starting with mostly used",  
  cex.names=0.8, col=c("darkblue","red"),space=c(0.2,0,0.2,0))
