Exercise 3.1 - missing what is d

[mesykkor]

In Excercise 3.1 there are defined a,b,c as numeric vector. Actually there is used d in the 3rd expression: a>b & a<c | a<c & a>d. A nano detail, but for someone used to math books immediately visible...

Thanks for your book and other stuff on your pages & Have a nice day,

Thanks for spotting this!

I've made a typo, the above should read: a>b & a<c | a<c & a>b.

The fix is on the way.
