I'm having trouble setting my axis range in r. My data only has values from 2 to 9 on the x axis but I want it to go from 1 to 10. Any quick tips please?
head(SS)
Phase Bed Site ACC X.M.SA
1 1 1 1 NG NO
2 1 1 2 NG NO
3 1 1 3 SG NO
4 1 1 4 SG NO
5 1 1 5 SG NO
6 1 2 1 SG NO
XMSA<-factor(SS$X.M.SA)
ACC<-factor(SS$ACC,ordered = TRUE,levels=c("NG","SG","LG","MG","HG"))
boxplot(ACC[XMSA=="MSSA"]~SS$Bed[XMSA=="MSSA"],
xlab="Bed",ylab="Growth",
las=1, yaxt="n",ylim=c(1,5),xlim=c(1,10))
axis(2, at=c(1,2,3,4,5),labels=c("NG","SG","LG","MG","HG"),las=1)
Answer
Without data, I tried to reproduce your plot error:
plot(x=as.factor(2:8),y=2:8,xlim = c(1,10)
Which gives the following plot:
Changing your plot to:
boxplot(x= as.numeric(as.character(SS$Bed[XMSA=="MSSA"])),
y= ACC[XMSA=="MSSA"]
xlab="Bed",ylab="Growth",
las=1, yaxt="n",ylim=c(1,5),xlim=c(1,10))
axis(2, at=c(1,2,3,4,5),labels=c("NG","SG","LG","MG","HG"),las=1)
Might solve your problem.
Edit
It seems that the formula changes to factors and orders it from 1 to the number of items, so I'll use your trick on the y axis to solve this.
boxplot(ACC[XMSA=="MSSA"]~SS$Bed[XMSA=="MSSA"],
xlab="Bed",ylab="Growth",
las=1, yaxt="n",ylim=c(1,5),xlim=c(0,9),xaxt="n")
axis(2, at=1:5,labels=c("NG","SG","LG","MG","HG"),las=1)
axis(1, at=0:9,labels=1:10,las=1)
