[arun]

HI,
Try this:
dat1<-read.table(text="
A              B            C      
1              10          1       
2              30          1       
3              50          1       
1000      1000        1        
1              10          2   
2              30          2   
3              50          2   
1000        1000      2        
",sep="",header=TRUE)

 dat1$R<-apply(dat1,1,function(x) x[1]+x[2]*x[3])
 dat1
#     A    B C    R
#1    1   10 1   11
#2    2   30 1   32
#3    3   50 1   53
#4 1000 1000 1 2000
#5    1   10 2   21
#6    2   30 2   62

Dear R-users,

I have dataset  with column A and B with1000 values,

For each of column C value (C = seq(1,1000,1), I want to repeat A and B
values and calculate R = A+B*C for each row.

I want to get output as

A              B            C         R
1              10           1         11
2              30           1         32
3              50           1         53
1000       1000        1        2000
1              10           2        21
2               30          2        62
3               50          2        103
1000        1000       2        3000

How can I do it using for loop?

Thanks
Shailly
