[R] How to extract integer in a data frame

[Gundala Viswanath]

Dear all,

I have a data frame that looks like this:

> dat

              V1      V2      V3
1          0.000       2 554889
2          2.001       0    9978
3          0.342       3    5263
4          123.000      0    3209
5          0.004       0    2434


I want to get a subset of that data frame where
the entry in V1 has (x.000) as its decimal.

yielding

> wanted_dat
              V1      V2      V3
1          0.000       2 554889
2          123.000   0    3209

What's the way to do it in R?
