R help - Feb 2018 - 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.

Regards,

Greg

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

> p+geom_point()

Cheers

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.

Hi Petr;

I would like to get a plot with names as they are in the original file.
They are chemical names and I have 733 in the my file. For example, let me
give to chemical names "*2-hydroxybutyrate/2-hydroxyisobutyrate*" and
"*palmitoyl-arachidonoyl-glycerol
(16:0/20:4) [1]**" .So, what should I put  [c(2,3,1)] part in the command:
iris$MySpecies<-factor(iris$Species, levels(iris$Species)[c(2,3,1)])

Regards,

Greg
