I find one row in my large dataset. But when I use the "rownames" for the
data on the 100,000 row, the result show nothing.
I try it by the following example, it still likes that.

> tst[rownames(tst)==100000,]
[1] x y
<0 rows> (or 0-length row.names)

##############

> tst=data.frame(x=1:200000,y=200000:1)
> tst[rownames(tst)==1,]
  x      y
1 1 200000
> tst[rownames(tst)==10000,]
          x      y
10000 10000 190001
> tst[rownames(tst)==100000,]
[1] x y
<0 rows> (or 0-length row.names)
> tst[100000,]
            x      y
100000 100000 100001

Is it a bug for R?
