Question

I have a VERY basic plot in R, and I’d like to solve two issues. Here is the code which produces the plot:

plot(o,n,bty="n",pch=21,cex=1.5,bg="gray",xlab="y",ylab="x",lwd=2)

And, here’s the plot

There are two unwanted behaviors of this plot that I’m trying to fix. And I don’t know how to do either one (nor do I understand why R doesn’t do these things already…)

1. The X and Y axes do not meet. There is a gap near the origin in this plot. I want to remove that. The axes should touch, just like any other graph.
2. The data extends past the axis is both the X and Y direction. This clearly is unwanted. How can I fix this without having to manually make my own axis. Seems like there should be something more intuitive here.

Answer 1

1. bty="l".

2. You may also want to use something like:

   xlim=c(0.02, 0.24), ylim=c(0.02, 0.24)
   

if you don’t like the default limits of your two axes.

In general, check out ?par for guidance on both of these and many other options.
