[R] regexp inside and outside brackets

[Adrian Dușa]

For the regexp aficionados, out there:

I need a regular expression to extract either everything within some
brackets, or everything outside the brackets, in a string.

This would be the test string:
"A1{0}~B0{1} CO{a2}NN{12}"

Everything outside the brackets would be:

"A1 ~B0 CO NN"

and everything inside the brackets would be:

"0 1 a2 12"

I have a working solution involving strsplit(), but I wonder if there is a
more direct way.
Thanks in advance for any hint,
Adrian
