Dear R users, I am a new R user. My problem is very simple: I want to add a linear regression line to the plot(type="p"), codes are as below: x<-c(10,20,40,80) y<-c(30,40,100,200) plot(x,y,type="p") lines(lm(x~y),col="red",lwd=1.5) I got only plot without linear line. Many thanks ahead for your advice!
