Ok, looking at the error it gives, it seems that there's a problem
with the current implementation of rxmerge where it doesn't deal with
some match arguments.
You can work around that problem for this example like this:
(,new) (,/(pat;,1+i.4) rxmatches test) rxmerge test
a
( 3,4
5,6 )
c
( 11,12
13,14 )
This makes the x argument to rxmerge be rank 1 and reduces the m
argument to rxmerge to rank 2 (which is what its current
implementation assumes you gave it).
I hope this helps,
