[R] scientific notation

[Bob Porter]

If I knew this, I have forgotten it:

Is there a way to force R to forgo use of scientific notation,
e.g. to use  .000029 instead of 2.9e-05?
(Aside from using formatC for example)
I run across this every now and then and work around it (multiple values by 100,
for example) but cannot find any way to deal with it otherwise.  A particularly
problematic place it pops up is in axis tick labels.  There appears to be no way
to force xx.xx notation...presumably because the width is so great.  Any
suggestions?
