[R] Decrete value check in a matrix

[arun]

Hi,

Try this:

dat1<-read.table(text="
ABC          XYZ     
1              2.5
3.4           4
5              6
5.6          6.7
",sep="",header=TRUE)

dat1[dat1$ABC ==as.integer(dat1$ABC), "ABC_RESULT"]<-TRUE
dat1[dat1$XYZ== as.integer(dat1$XYZ),"XYZ_RESULT"]<-TRUE
dat1[is.na(dat1)]<-FALSE
dat1
  ABC XYZ ABC_RESULT XYZ_RESULT
1 1.0 2.5       TRUE      FALSE
2 3.4 4.0      FALSE       TRUE
3 5.0 6.0       TRUE       TRUE
4 5.6 6.7      FALSE      FALSE

A.K.

Hi Arun,

Can you please help me,

Here i have a Data frame (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 solution fast. Its urgent thtz y. 

Antony.
