[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")) [[alternative HTML version deleted]] ___ R-sig-ecology mailing list R-sig-ecology@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-ecology
Re: [R-sig-eco] Change ggplot legend
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?

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 On Thu, Apr 16, 2015 at 11:36 AM, Luis Fernando García wrote: > 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")) > > 2015-04-16 6:26 GMT-03:00 Roman Luštrik : > >> 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 >> >> >> On Thu, Apr 16, 2015 at 11:11 AM, Luis Fernando García < >> luysgar...@gmail.com> wrote: >> >>> Dear R experts, >>> >>> I am trying to make a new plot.

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")) 2015-04-16 6:26 GMT-03:00 Roman Luštrik : > 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 > > > On Thu, Apr 16, 2015 at 11:11 AM, Luis Fernando García < > luysgar...@gmail.com> wrote: > >> Dear R experts, >> >> I am trying to make a new plot.

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"? http://www.cookbook-r.com/Manipulating_data/Renaming_levels_of_a_factor/ grs, Stijn On 04/16/2015 11:26 AM, Roman Luštrik wrote: 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?
