[R-sig-Geo] Trouble with leglabs()

[Susumu Tanimura]

Hi there,

This may be a silly question here, but I cannot solve a problem with
leglabs().  

> breaks <- c(0,300000, 600000, 900000,1200000,10000000)
> leglabs(breaks)
[1] "under 3e+05"     "3e+05 - 6e+05"   "6e+05 - 9e+05"   "9e+05 - 1200000"
[5] "over 1200000"

I do not need exponential expression but sequential zero.  It is very
happy if you give me some advice.
