[R] Decrete value check in a matrix

[Rantony]

Hi All,

Here i have an Dataframe (or) Matrix like this,

MyMatrix <-
ABC          XYZ
------        -------
1              2.5
3.4           4
5              6
5.6          6.7

Here i need to check each column value having decrete value or not ?.
If that particular coulmn-value having decrete value, then the result should
be
TRUE/FALSE respectively in the result column.
Finally, i need to get the result as  Dataframe (or) Matrix form like this

ABC          XYZ      ABC_RESULT               XYZ_RESULT
------        -------     --------------------            
--------------------
1              2.5                 TRUE                       FALSE
3.4           4                    FALSE                     TRUE
5              6                    TRUE                        TRUE
5.6          6.7                  FALSE                     FALSE

- Can any one help me fast ? 

Antony.
