R ggplot2 X軸繪製爲水平

我不能強迫R用x軸以升序繪製我的數據。當我繪製該數據中，x軸是在順序1，10，11，12，2，3，...R ggplot2 X軸繪製爲水平

library(ggplot2) 
BradfordProteinData<-read.csv(normalizePath('data/ch3/bpa.csv')) 
BPD<-BradfordProteinData[-(1),] 
xx<-BPD[,1] 
yy<-BPD[,3] 
xx 
yy 
par(mar=c(1,1,1,1)) 
ggplot(BPD) + geom_point(aes(x=Hour, y=OD600)) 
qplot(xx,yy, geom = c("point", "smooth")) 
qplot(sort(Hour, decreasing=FALSE), OD600, data = BPD, geom = c("point", "smooth"))

值xx和yy是class(xx) # factor。我的SE點太低，無法插入圖片，但這裏是我爲.csv

Hour,OD600,OD600,OD600,Average,StdDev 
Hour,R1,R2,R3,Average,StdDev 
1,0.037,0.040,0.031,0.036,0.003 
2,0.048,0.044,0.042,0.044,0.002

數據嘗試

sort(as.numeric(Hour), decreasing=FALSE)

這是你的字符串「10」，「11」將因此被視爲數字按數值排序而不是字符串值
