add a linear regression line to the plot
...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! Xipei Wang [[alternative HTML version deleted]]

plot continuous data vs clock time
...quot;15:30", "21:23") x<-as.POSIXct(strptime(paste(x),"%H:%M")) plot(y~x, type="p") I got the plot, but if I want to plot the x range from 1:20 to 9:25, how can I set the xlim argument? Any suggestions about the clock time plotting would be appreciated. Xipei Wang [[alternative HTML version deleted]]
