All,
The first use of expression produces a double subscript while the second does not.

plot(1:10, 1:10)
text(par("usr")[1] - .5, 5, adj = 1, labels = expression(hat(b)[11]), xpd =

If you want "0i" as subscript, use

  expression(hat(b)[0*i])

(0i is complex and represented by 0+0i afterwards)

Or does "double" mean you want i as subscript of 0? Then just try

  expression(hat(b)[0[i]])
