How would you define better?
If you are looking for economy of expression, I'd probably leave that
leading space in place, and stick the file in the J system directory:
/:~(~.,.<@#/.~)',' {:@cut&> 'b' freads 'jconf2014'
┌────────────┬──┐
│ Canada │14│
├────────────┼──┤
│ Denmark │2 │
├────────────┼──┤
│ Finland │2 │
├────────────┼──┤
│ Germany │1 │
├────────────┼──┤
│ Hong Kong │2 │
├────────────┼──┤
│ Switzerland│1 │
├────────────┼──┤
│ UK │2 │
├────────────┼──┤
│ USA │20│
└────────────┴──┘
Note that I've assumed you've used copy and paste to grab just the attendee
list from a rendered instance of the conference page.
Note also that this is an equivalent expression in my case (though, with a
messy file, freads is probably safer to use):
/:~(~.,.<@#/.~){:@cut~&',';._2 fread 'jconf2014'
Thanks,
