横轴上的右名称

Question

目标：
我想在箱线图的水平轴上使用月份名称 "January" 和 "February"。

问题：
我试着去做，但我失败了。将 "Month" 和 "Names" 作为横轴文本是不正确的。

mydata

#       Month Count
# 1   January    10
# 2   January    11
# 3   January    22
# 4   January    55
# 5   January     4
# 6   January    88
# 7  February    44
# 8  February    40
# 9  February    30
# 10 February    28

这里是 mydata 的 dput :

mydata<-structure(list(Month = structure(c(2L, 2L, 2L, 2L, 2L, 2L, 1L, 
1L, 1L, 1L), .Label = c("February", "January"), class = "factor"), 
    Count = c(10, 11, 22, 55, 4, 88, 44, 40, 30, 28)), .Names = c("Month", 
"Count"), row.names = c(NA, -10L), class = "data.frame")

这是 boxplot(mydata) 的结果：

Answer 1

你可以这样做：

boxplot(df$Count~df$Month)

它将 return :

如果要先显示一月再显示二月，请执行：

df[,1]<-factor(df[,1],levels=c('January','February'))
boxplot(df$Count~df$Month)

或者只是：

boxplot(df$Count~df$Month,names=c('January','February'))
