I do not know functions like ?pretty that Rui used, nor ?quantile or ?cut. It is a difficulty in learning R where the internet or sites like this one are the "teacher." 

Yes, that's unfortunately true.

In this particular case I've learned about pretty() because I used to 
use hist(., plot=FALSE) to get pretty breakpoints. And hist's 
documentation says it uses pretty().


There are plenty of books, but they too take one approach to solve a 
problem rather than "here is a problem" and "these are all possible 
solutions." I appreciate seeing alternative solutions.

This thread is a good example of a "teacher" with several solutions, 
there are many more threads like this.
