[R-sig-eco] Change ggplot legend

[Luis Fernando García]

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"))
