Hello Peter, I checked for the "levels()" and "reorder()", but I can't make it work. R classifies the "Groups" (factor) by alphabetical order, but I would just like to make him understand that it is ordered (is.ordered()) in my data frame.
Here is my code : abs1<-spleen*p1*p2*cd8 length(abs1) # = 13 abs<-c(0.499,0.73,0.5,0.75,abs1) symb<-rep(c(17,15,17,15,19),times=c(2,2,5,5,3)) noms<-rep(c("WT (NI)","Bim-/-Bid-/- (NI)","WT","Bim-/-Bid-/-","Bim-/-Noxa-/-"),times=c(2,2,5,5,3)) df<-data.frame(abs,symb,noms) ehplot(df$abs,df$noms,offset=0.1,intervals=10,median=FALSE,pch=df$symb, xlab="Recipient mice strain (CD45.2)",ylab="# CD8alpha DC x 10^6", main="Absolute number of CD8alpha DCs in spleen",ylim=c(0,3)) Thank you for your help Dusan -- View this message in context: http://r.789695.n4.nabble.com/Switch-Groups-in-ehplot-x-axis-tp4649485p4649632.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
