我的最终情节没有显示因子A的0水平。
标题数据:
month A B
mayo 20 6.9
mayo 16 16.3
mayo 14 19.8
mayo 12 12.6
mayo 9 19.5
mayo 8 65.4
mayo 18 11.7
mayo 17 22.8
mayo 15 34.3

mayo 11 43.7
mayo 10 21.6
mayo 21 20.9
mayo 7 7.3
mayo 22 32.3
mayo 19 17.8
mayo 0 96.0
data.frame的结构:
'data.frame': 17 obs. of 3 variables:
$ month : chr "mayo" "mayo" "mayo" "mayo" ...
$ A : Factor w/ 18 levels "0","7","8","9",..: 15 11 9 7 4 3 13 12 10 8 ...
$ B: num 6.9 16.3 19.8 12.6 19.5 65.4 11.7 22.8 34.3 36.9 ...
ggplotting的我的R代码:
ggplot(data,aes(x = A, y = B)) +
geom_bar(stat="identity",size=1.5,colour = "black",fill="green")
更新
我的R代码出了问题。 0级包含在月份==" mayo&#34 ;,而不是月份==" abril" (包括在完整数据中)。
确实,它没有显示0级:
ggplot(data[data$month=="abril",],aes(x = A, y = B)) +
geom_bar(stat="identity",size=1.5,colour = "black",fill="green")
由于
答案 0 :(得分:1)
似乎为我工作
data <- data.frame(month=rep('mayo',17),
A=factor(c(20,16,14,12,9,8,18,17,15,13,11,10,21,7,22,19,0)),
B=c(6.9,16.3,19.8,12.6,19.5,65.4,11.7,22.8,34.3,36.9,43.7,21.6,20.9,7.3,32.3,17.8,96.0),
stringsAsFactors = F)
ggplot(data,aes(x = A, y = B)) +
geom_bar(stat="identity",size=1.5,colour = "black",fill="green")
str(data)
