Subject: Difference between a[[i]] and a[i]
I think the thing that escaped me for quite a while was tracking down
the syntax to specify elements of a list element:
x[[5]][3:7] to get items from within the 5th element of x.
Seems IIRC there are some types of variables for which the form
x$thing[3:7] fails and others for which it works fine (where the fifth
element of x is named 'thing'). But I might be dreaming.
