wish: corrgram to respect par(mar) #12
Description
Hi Kevin,
it's me again ... Thanks for reacting so promptly to previous comments! This time, I have a more difficult one (I believe): it's hard to impossible to add annotation or a legend to a corrgram, due to the fact that you manipulate par settings in the function and reset them to previous state before exiting.
If corrgram would add a legend itself (is this still on your TODO list?), this might be OK. However, it's almost impossible to anticipate all user needs in advance, and it would therefore, in my opinion, be very useful if corrgram would respect a user's margin settings and allow users to write, plot, ... to those margins subsequently. If this is not possible because of the function's design, there could be an option that prevents the reverting of par to its previous state, so that the user can work with the resulting figure (like e.g. done in package kohonen for plotting SOMs).
Best, Ulrike
