[R] Displaying trailing zeroes

[Lucke, Joseph F]

round(12.01,1) will give the answer 12, not 12.0 or even 12.  To make a
table look nice, I need to display the trailing zero so that just as
round(12.05,1) yields 12.1, round(12.01) yields 12.0. I cannot find an
answer in print() or format() or options().  Any suggestions would be
appreciated.
