Hi What do you mean „without reordering the names“. Factor variable is ordered according to its levels and you can freely change the ordering. This is why factors are useful and worth to use in many cases instead of character vectors.
See this result > iris$MySpecies<-factor(iris$Species, levels(iris$Species)[c(2,3,1)]) > p<-ggplot(iris, aes(x=Sepal.Length, y=Species)) > p+geom_point() > p<-ggplot(iris, aes(x=Sepal.Length, y=MySpecies)) > p+geom_point() > Cheers Petr From: greg holly [mailto:mak.hho...@gmail.com] Sent: Friday, February 16, 2018 3:56 PM To: PIKAL Petr <petr.pi...@precheza.cz> Cc: r-help mailing list <r-help@r-project.org> Subject: Re: [R] Putting 733 discrete categories on Y-axis in qqplot2 as they are Hi Petr; Thanks. I do save the result in pdf by using the following command. ggsave("z7.pdf", p4, height = 95, width = 8, device=pdf, limitsize = F,dpi=300) I can achieve the y axis with 733 levels. But I need get the plot WITHOUT reordering the names.

You probably can achieve the y axis with 733 levels if you do not use limits in scale. Just from curiosity, standard page has 30 lines, so your axis should stretch to more than 20 pages. Or you need to shrink your y axis 20 times. Both options will give you unreadable results.
