works well, case 4 (trend restricted to the cointegration space)

Hm, this looks wrong indeed as a matrix product. Do I guess correctly
that you have a rank higher than 1? If so, then it could be that this
case has never been properly tested.
The same problem would probably also happen for a restricted constant,
could you try that just to check (also with rank > 1)?
P.S. Is it possible to change the pink color in IRFs graphs from the
SVAR package?
Have you tried editing the produced plots? Back in the old days that
would have ruined the whole plot, but hopefully this is more robust now
(and if not, it's also interesting to know).
thanks for the report,
sven
