翻转水平条形图（）（基数 R）中条形图（y 轴）的顺序

Question

我一直在寻找我可能遇到的基本问题的解决方案，但一直没有找到！

我正在处理以下数据 uk_twit_dm_semantic:

structure(c(0.02, 0.98, 0, 1, 0.2, 0.8, 0.82, 0.18, 0.98, 0.02, 
0.05, 0.95, 0.41, 0.59, 0.81, 0.19, 0.32, 0.68, 0.9, 0.1, 0.45, 
0.55), .Dim = c(2L, 11L), .Dimnames = list(c("EE", "ER"), c("will can", 
"will shall", "would could", "would might", "will might", "would should", 
"will should", "will would", "will could", "will may", "Total"
)))

我正在处理此数据的水平堆叠条形图，但我希望反转条形的顺序（例如，will 可以是最顶层的条形，然后是向量的每个元素，直到“总计” ，最底部的栏）。出于某种原因， horiz=TRUE 给了我相反的顺序。如何翻转订单？

barplot(uk_twit_dm_semantic, col=coul, border="white", horiz=TRUE,legend=rownames(uk_twit_dm_semantic))

祝一切顺利，

Answer 1

一个想法可能是在启动绘图代码行之前反转数据框的列顺序

# 1- Reversing order of columns   
uk_twit_dm_semantic_rev <- uk_twit_dm_semantic[, rev(colnames(uk_twit_dm_semantic))]

# 2- Launching the plot with reversed columns
barplot(uk_twit_dm_semantic_rev, col=coul, border="white", horiz=TRUE, legend=rownames(uk_twit_dm_semantic_rev))

Answer 2

使用 order 和 col 的想法相同：

barplot(uk_twit_dm_semantic[,order(ncol(uk_twit_dm_semantic):1)],col=c("red","blue"), border="white", horiz=TRUE,legend=rownames(uk_twit_dm_semantic))
