Thanks,
Now its work, but I dont get to change te legend position. Look:
ggplot(data1, aes(x=x1, y=y1))+
geom_point()+
geom_smooth(method="glm", family="gaussian",aes(linetype="equation1"))+
geom_smooth(aes(x=x1, y=y1, linetype="equation2"),data=data2,
method="glm", family="gaussian")+
scale_linetype_manual(values =
c("solid","dashed"),name="Equations",labels=c("Equation 1","Equation
2"),guide="legend")+
theme(plot.title = element_text(lineheight=.8,
face="bold"),legend.position="top")+
theme_bw()
Now the legend work, but the argument legend.position="top" in theme()
function dont work. I try to change the order of commands, but without
effects.
Any idea?
Thanks
Ronaldo
