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 it’s 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
