[英]resorting stacked barplot in r
I am trying to flip the order of a stacked barplot in R. 我试图在R中翻转堆积的条形图的顺序。
Here is a sample using the mtcars dataset. 以下是使用mtcars数据集的示例。
#using mtcars, create a table
counts <- table(mtcars$vs, mtcars$gear)
#edit row names of table
row.names(counts)[1] <- "VS = 0"
row.names(counts)[2] <- "VS = 1"
#create barplot
barplot(counts, legend = row.names(counts))
I want to flip the order of the heights of the bars, so that VS = 1 is on the bottom or VS = 0. The x-axis should remain sorted as 3,4,5. 我想翻转条形高度的顺序,以便VS = 1位于底部或VS = 0.X轴应保持排序为3,4,5。
Simply flip the order of the rows in counts
: 只需按counts
翻转行的顺序:
foo <- counts[c(2,1),]
barplot(foo, legend = row.names(foo))
Of course, the bottom bars are still colored darker, so this also flips the color coding. 当然,底部条纹仍然是较暗的颜色,因此这也会改变颜色编码。 If you want to keep that, adjust the col
argument to barplot
. 如果要保留它,请将col
参数调整为barplot
。
