[R] Manipulate strings reordering some elements

[Igor Sosa Mayor]

many thanks, Berend.

It works well... but with a problem because i was not completely clear
in my first email.

It works with cases such as:
Franco (El)
Regueras (Las)

but not with other cases such as:
Fauces de San Andrés (Las)

any hints? or meaybe if it is very complicated, any short explanation of
the perl expression you wrote (as far as I can understand, the point is
this \\3 \\1...).

thx again
