
James
           Thank you for response. I am working on treatment for missing data for both bivariate and multivariate normal data. Coming back to example. My problem was that once we do execute this command 
x.1 <- read.table('/tempxx.txt', fill=T)


How can access the particular column say X8 and all its values so that I could assign some other operations on them.
Because if I say 
print.default(x.1)

the result..

   V1  V2
1  X    y
2  8    10
3 11   1 4
4 16   16
5 18   15
6  6    20
7  4     4
8 20   18
9 25    22


and I want to access V1  values......


thank you
regards
Kunal
