All,  

The first use of expression produces a double subscript while the second does not. I searched in ?plotmath and the archives and didn't find anything. I'm sure I'm missing something obvious but can't seem to find. any suggestions much appreciated.  

Cheers,
David    

plot(1:10, 1:10)
text(par("usr")[1] - .5, 5, adj = 1, labels = expression(hat(b)[11]), xpd = TRUE)
text(par("usr")[1] - .5, 5, adj = 1, labels = expression(hat(b)[0i]), xpd = TRUE)
