给出以下数据集:
Output<- read.table(text = "Type 2012-06-30' 2012-09-30
1 Market 2 3
2 Geography 3 -2
3 Industry -1 5 ",header = TRUE,sep = "",row.names = 1)
我尝试准备数据以便使用ggplot2包并创建一个带负值的堆积条形图。这是我使用的基本图表序列:
Output$row <- seq_len(nrow(Output))
dat2 <- melt(Output, id.vars = "row")
但是这给了我:
dat2
row variable value
1 1 Type Market
2 2 Type Geography
3 3 Type Industry
4 1 X2012.06.30. 2
5 2 X2012.06.30. 3
6 3 X2012.06.30. -1
7 1 X2012.09.30 3
8 2 X2012.09.30 -2
9 3 X2012.09.30 5
理想情况下,在&#39;行中列而不是数字我会有Market io 1,Geography io 2,Industry io 3以便我用不同的(市场,地理,行业)类别填充我的条形图而不是1-2-3。还有行1到3应该删除dat2,因为它们不对应于四分之一数据。谢谢!
dat1 <- subset(dat2,value >= 0)
dat3 <- subset(dat2,value < 0)
ggplot() +
geom_bar(data = dat1, aes(x=variable, y=value, fill=row),stat = "identity") +
geom_bar(data = dat3, aes(x=variable, y=value, fill=row),stat = "identity") +
scale_fill_brewer(type = "seq", palette = 1)
答案 0 :(得分:0)
我在下面试了一下,但我对你粗体问题很困惑。数据的奇怪格式似乎是由使用id.vars = "row"
引起的,但请在需要时澄清。
