Hey All, I need to apply different regression lines to different group on my ggplot, and here is the code I use:
qplot(x=Var1,y=Var2,data=df,color=SiteID,group=SiteID)+geom_point()+geom_smooth(method='lm',formula=log(y)~I(1/x),se=FALSE,size=2) However the regression for different groups is as below: AL1/AL2: log(y)~I(1/x) AL3: log(y)~log(x) How can I apply each regression equation on the same ggplot? Also I have an issue that if I use the code above, the regression lines are not overlapped on top of my data points. Thanks for your help!
