Hi Antony,
Try this,
> Obj_Name<-da$AGE
> Obj_Name
[1] 20 30 40 30 25
da[Obj_Name>=30 & Obj_Name<=40, "TRUE/FALSE"]<-TRUE
colnames(da)<-c("NAME","Obj_Name","PLACE","ELIGIBLE")
> da
NAME Obj_Name PLACE ELIGIBLE
1 ABC 20 INDIA NA
2 XYZ 30 FRANCE TRUE
3 PQR 40 USA TRUE
4 MNO 30 KENYA TRUE
> da[is.na(da)]<-""> da
NAME Obj_Name PLACE ELIGIBLE
1 ABC 20 INDIA
2 XYZ 30 FRANCE TRUE
3 PQR 40 USA TRUE
4 MNO 30 KENYA TRUE
5 DEF 25 AUSTRALIA
I hope this helps.
A.K.

Subject: [R] Use variable inside Function for updating the matrix
Hi,
Here i have a data frame like this,
frame name is "dat"
*NAME AGE ELIGIBLE*
A 20
B 14
C 35
D 10
E 50
In this, i want to change the column '*ELIGIBLE*' status to '*YES*' If, AGE
between 18 to 35
Which means that, i should get a put like this...
*NAME AGE ELIGIBLE*
A 20 YES
B 14
C 35 YES
D 10
E 50
----------------------------------------------
Now i got the solution for this,
dat[dat$AGE<=35 & da$AGE>18,"ELIGIBLE"]<-YES
My issue is, i assigned AGE to a variable and that variable i tried inside
the function.
for eg:-
*Obj_Name* <- AGE
dat[dat$*Obj_Name*<=35 & da$*Obj_Name*>18,"ELIGIBLE"]<-YES
Now, what is i getting the error !.
So,could you please help me, what is the solution *pass column name through
*variable to this function ?
Can i get immediate solution please ?
- Thanks
Antony
