Hi,
I also think that this is desirable: I so often thought that this may be
useful in the contexts of a matrix and of an array (even series?).
Right; let me just remind myself and others that the Python-esque syntax
of using negative numbers like -1 wouldn't work in gretl/hansl, since
that already means to drop the associatied row/col, which is also a nice
feature. As in:
? print I(3)[-1,]
0 1 0
0 0 1
cheers
