我想繪製箱形圖。我有超過1000行,但當我繪製它們時,它只顯示幾個條目。無法在R中繪製所有數據繪圖
數據集: https://www.dropbox.com/s/tgaqfgm2gkl7i3r/maintenance_data_updated.csv
#Start of Box plot Temperature
training_data <- read.csv("C:/Users/akhan/Documents/maintenance_data_updated_2.csv", stringsAsFactors = TRUE)
library(dplyr)
dt_temperature <- select(training_data, Runtime, Defect, Machine, Temperature, Plant)
dt_temperature$Machine_Plant = paste(dt_temperature$Machine,dt_temperature$Plant,sep = "_")
attach(dt_temperature)
class(Temperature)
class(Defect)
class(Runtime)
class(Machine)
?boxplot
boxplot(Temperature ~ Machine_Plant)
任何人都可以請給一個提示如何解決?
你確定Machine_Plant變量是一個因素嗎?嘗試:boxplot(溫度〜as.factor(Machine_Plant)) –
