如何让我的行名称出现在我的 x 轴上？我的变量中的数字显示为 y 轴？

Question

我创建了一个数据框，其中国家/地区作为行名，百分比作为 obs。来自变量，但是在制作直方图时，变量的百分比似乎占据了 x 轴，而国家/地区名称甚至不存在。我如何才能使国家名称在 x 轴上，变量在 y 轴上？

Country <- c('Albania','Armenia','Austria','Belarus','Belgium','Bosnia and Herzegovina','Bulgaria','Croatia','Cyprus','Czechia','Denmark','Estonia','Finland','France','Georgia','Germany','Greece','Hungary','Iceland','Ireland','Italy','Latvia','Lithuania','Luxembourg','Malta','Moldova','Montenegro','Netherlands','Norway','Poland','Portugal','Romania','Russia','Serbia','Slovakia','Slovenia','Spain','Sweden','Switzerland','Turkey','Ukraine','United Kingdom')
Anxiety.Disorders <- c(3.38,2.73,5.22,3.03,4.92,3.70,3.84,3.74,5.61,3.59,5.18,3.01,3.59,6.37,2.46,6.37,5.58,3.69,5.15,5.66,5.57,3.04,3.06,5.19,5.14,2.77,3.55,6.43,7.33,3.68,5.52,3.41,3.02,3.60,3.61,3.60,5.14,5.16,5.28,3.85,3.09,4.43)
Depressive.Disorders <- c(2.42,3.16,3.66,4.84,4.35,2.88,3.30,3.60,3.88,3.25,3.62,4.78,5.08,4.55,2.98,4.42,4.56,3.53,3.55,4.37,3.94,4.44,5.20,3.95,3.69,3.77,2.96,4.34,3.95,2.72,5.27,2.88,4.36,3.15,2.87,3.58,3.91,4.84,4.17,3.76,5.02,4.35)
Bipolar.Disorder <- c(0.72,0.77,0.95,0.73,0.91,0.79,0.67,0.77,1.04,0.75,0.99,0.71,0.99,0.93,0.67,0.79,0.93,0.74,0.97,0.80,0.95,0.71,0.73,0.95,0.97,0.67,0.74,0.94,0.85,0.76,0.97,0.78,0.70,0.74,0.76,0.75,0.97,1.04,0.98,0.85,0.73,1.05)
G08 <- data.frame(Country, Anxiety.Disorders, Depressive.Disorders, Bipolar.Disorder)
row.names(G08) <- G08$Country
G08[1] <- NULL

hist(G08$Anxiety.Disorders)

Answer 1

我使用 melt() 调用为每行创建一个观察值。然后，我使用 ggplot 生成条形图。

library(ggplot2)
library(reshape2)

Country <- c('Albania','Armenia','Austria','Belarus','Belgium','Bosnia-Herzegovina','Bulgaria','Croatia','Cyprus','Czechia','Denmark','Estonia','Finland','France','Georgia','Germany','Greece','Hungary','Iceland','Ireland','Italy','Latvia','Lithuania','Luxembourg','Malta','Moldova','Montenegro','Netherlands','Norway','Poland','Portugal','Romania','Russia','Serbia','Slovakia','Slovenia','Spain','Sweden','Switzerland','Turkey','Ukraine','United Kingdom')

Anxiety.Disorders <- c(3.38,2.73,5.22,3.03,4.92,3.70,3.84,3.74,5.61,3.59,5.18,3.01,3.59,6.37,2.46,6.37,5.58,3.69,5.15,5.66,5.57,3.04,3.06,5.19,5.14,2.77,3.55,6.43,7.33,3.68,5.52,3.41,3.02,3.60,3.61,3.60,5.14,5.16,5.28,3.85,3.09,4.43)

Depressive.Disorders <- c(2.42,3.16,3.66,4.84,4.35,2.88,3.30,3.60,3.88,3.25,3.62,4.78,5.08,4.55,2.98,4.42,4.56,3.53,3.55,4.37,3.94,4.44,5.20,3.95,3.69,3.77,2.96,4.34,3.95,2.72,5.27,2.88,4.36,3.15,2.87,3.58,3.91,4.84,4.17,3.76,5.02,4.35)

Bipolar.Disorder <- c(0.72,0.77,0.95,0.73,0.91,0.79,0.67,0.77,1.04,0.75,0.99,0.71,0.99,0.93,0.67,0.79,0.93,0.74,0.97,0.80,0.95,0.71,0.73,0.95,0.97,0.67,0.74,0.94,0.85,0.76,0.97,0.78,0.70,0.74,0.76,0.75,0.97,1.04,0.98,0.85,0.73,1.05)

G08 <- data.frame(Country, Anxiety.Disorders, Depressive.Disorders, Bipolar.Disorder)

G08melt <- melt(G08, "Country")

G08.bar <- ggplot(G08melt, aes(x = Country, y=value)) +
  geom_bar(aes(fill=variable),stat="identity", position ="dodge") + 
  theme_bw()+ 
  theme(axis.text.x = element_text(angle=-40, hjust=.1))

G08.bar

Answer 2

看你的问题，我认为你试图做一个分组柱状图而不是直方图。您可以使用 graphics 包中的 barplot 函数直接绘制。但在此之前，您需要将 dataframe 转换为 matrix。我从 G08.

中删除了第一列

mat<-G08[,-1]

现在只需简单地在矩阵 mat 的转置上使用 barplot 函数，并使用 barplot 的 names 参数将国家名称写在x 轴：

barplot(t(mat),beside=T,col=c('red','blue','gold'),border=NA,names=G08$Country,cex.names=0.45,las=2)
par(new=T)
legend('topright',c("Anxiety","Depressive","Bipolar"),fill=c("red","blue","gold"),cex=0.5,title='Disorder types')

建议： 对于图表中更多的'fresh air'，您可以在barplot中设置beside=F并获得堆积柱形图：

How do I make my row names appear on my x axis? And the numbers on from my variables appear as the y axis?
