[R] a weird "cut" question

[Erin Hodgess]

Dear R People:

I have the following data:

> ail.df[,1]
[1] 47677 47602 47678 47905 47909 47906 47605 47673 47607
> cut(ail.df[,1],breaks=3)
[1] (4.76e+04,4.77e+04] (4.76e+04,4.77e+04] (4.76e+04,4.77e+04]
[4] (4.78e+04,4.79e+04] (4.78e+04,4.79e+04] (4.78e+04,4.79e+04]
[7] (4.76e+04,4.77e+04] (4.76e+04,4.77e+04] (4.76e+04,4.77e+04]
Levels: (4.76e+04,4.77e+04] (4.77e+04,4.78e+04] (4.78e+04,4.79e+04]
>
so I have cut ail.df[,1] into 3 levels.  However, the second level
never appears in the data set.

Is there a way to set cut such that every level appears, please?

thanks in advance,
Sincerely,
Erin
