[R-sig-eco] Change ggplot legend
Dear R experts,
I am trying to make a new plot. I have already finished and I just want to
change the color for the axis number and the legends, I have tried to make
the last function by removing the legend and adding a new one but it did
not work.
If any of you knows how to correct this, I would really appreciate it. My
aim is to rename the series as "Sp1" and "Sp2".
Thanks in advance!
HEre is the plot code
p <- ggplot(t,aes(x=Ratio,y=Time)) + geom_point(aes(shape=factor(Sp)))
p + geom_smooth(aes(linetype=factor(Sp), ),colour="black", method='lm',
se=F)+theme(panel.grid.major = element_blank(), panel.grid.minor =
element_blank(),panel.background = element_blank(), axis.line =
element_line(colour = "black"))+
theme(legend.position="none")+#Remove legend to add a new one
scale_shape_discrete(name ="Species",labels=c("Sp1", "Sp2"))

Can you provide a reproducible example (using some available dataset or
simulate some data) and perhaps mark on the picture what you want to have
changed?
Cheers,
Roman

Re: [R-sig-eco] Change ggplot legend
To change the axis text color, use theme().
Compare
library(ggplot2)
ggplot(PlantGrowth, aes(x=group, y=weight)) +
geom_boxplot()
to
ggplot(PlantGrowth, aes(x=group, y=weight)) +
geom_boxplot() +
theme(axis.text = element_text(color = "black"))
To change legend title, see
http://www.cookbook-r.com/Graphs/Legends_(ggplot2)/#modifying-the-text-of-legend-titles-and-labels
Cheers,
Roman

Re: [R-sig-eco] Change ggplot legend
Sure!
I can provide a sample graph
I want to get the axis values to be black and remove the legend with the
name "factor(Sp)" and get the values for the axis to be black!
Thanks!
This is the code
t<-read.table ("covartimesfinal2.txt", header=T)
attach(t)
p <- ggplot(t,aes(x=Ratio,y=Time)) + geom_point(aes(shape=factor(Sp)))
p + geom_smooth(aes(linetype=factor(Sp), ),colour="black", method='lm',
se=F)+theme(panel.grid.major = element_blank(), panel.grid.minor =
element_blank(),panel.background = element_blank(), axis.line =
element_line(colour = "black"))+
scale_shape_discrete(name ="Species",labels=c("Sp1", "Sp2"))

Re: [R-sig-eco] Change ggplot legend
Why don't you just adapt it in the dataframe and make sure the levels in
the Sp column are renamed to "Sp1" and "Sp2"?
