The following commands only show the data in 'y'. I'm wondering how to
show the data in 'x' as well. I also want to add a legend to show that
blue points corresponds to 'x' and yellow points correspond to 'y'.
Could somebody let me know what the correct commands should be?
x=rbind(c(10,11),c(10,11))
y=cbind(-1:0,-1:0)
plot(y,col='yellow')
points(x,col='blue')
Hi Peng,
To show the "x" points, you will have to set both the xlim and ylim
arguments:
plot(y,col="yellow",xlim=c(-1,11),ylim=c(-1,11))
points(x,col="blue")
I'm not sure why you are passing the points as matrices, but this means
that the "x" points are the same.
