[R] Spacing Between Elements in Lattice Legend

[Bert Gunter]

1. Always cc the list, which I have done here (unless you want to say
something that truly should be private).

2. Ahh... I see. I don't believe you can do it using auto.key, which
feeds it's list to the simpleKey() function: the price you pay for
keeping it simple is that you lack fine control over details such as
the rectangle height, which is (I believe) what you want. If you
replace the auto.key=  list via the following key= list, I think you
get what you want by controlling rectangle height to your taste: e.g.

key =               list(title = "Year",
                       text = list(c("2015","2016")),
                       rectangles = list(height=.5,
                           col= c("blue","red")),
                       columns=1,space="right",padding.text=3)


If this is *NOT* what you want, do cc the list in any reply.


Oh, and incidentally, your code mistakenly had the "main" argument replicated.


Cheers,
Bert
