Changing ggplot2 legend key/title to custom text

BARLAS Marios 247554
Hi all,

ok I have this issue:

I want to change my graphs legends to custom text, often requiring the use of superscripts/subscripts
I tried to use this instruction I found on stack overflow:

labs(x = "R(Ohm)", y= "CDF", aesthetic= " Content (%)" )

but it wont' seem to work.

Also tried bquote for super/ subscripts

xlab(bquote(~x~/(~x~ + ~MO[2]~)* '(%)'))

but I get an error that the / operator is not recognized.

Any ideas on how I can solve these issues ?

Thanks in advance,
Marios Barlas

Hi

There are plenty of examples
https://stackoverflow.com/questions/6202667/how-to-use-subscripts-in-ggplot2-legends-r
https://stackoverflow.com/questions/19507742/using-expressionpaste-to-insert-math-notation-into-a-ggplot-legend

which you can modify.

If you say

"but it wont' seem to work"

how can we know what does it mean?

Plotmath expressions are rather tricky, especially if you do not use them often. You need some experimenting.

Cheers
Petr

BARLAS Marios 247554
Hi Petr and thanks for your reply,

That's the problem I don't want to modify the labels of my legends but the title of the legend in itself inserting my custom text :)

Take for example the 1st graph in this tutorial
http://www.sthda.com/english/wiki/ggpubr-r-package-ggplot2-based-publication-ready-plots
I want to change the "sex" in "sex subscript 2" or " (sex/sex[2]+Q)

Thanks again,

Re: Changing ggplot2 legend key/title to custom text

PIKAL Petr
Hi

I usually use google. It is quite powerful.

Search
ggplot legend title

results in
http://www.cookbook-r.com/Graphs/Legends_(ggplot2)/

from which you could find a way how to modify legend.

library(ggplot2)
bp <- ggplot(data=PlantGrowth, aes(x=group, y=weight, fill=group)) + geom_boxplot()
bp
bp + scale_fill_discrete(name="Experimental\nCondition",
                          breaks=c("ctrl", "trt1", "trt2"),
                          labels=c("Control", "Treatment 1", "Treatment 2"))


For plotmath (subscripts, ...) see

?plotmath

e.g.

plot(1,1, main=expression("sex"[2]), sub=expression("sex"^"2"))
text(1,.8,expression(over("sex", "sex"[2])))

Cheers
Petr
