Thanks a lot. I’ve got it just now.

Thanks for your reply.
You're right, here is what I did:

Thanks guys. but I'm a bit confused. the input is the first column (z[,1]
and z1[,1]).
How is it possible that a subset of a non-NA vector, contains NA?

It is a bit more obvious with integer indexing, as in color[race]: if race is
NA you don't know what color to put in, but the result should be the same
length as race.
With logical indices, the behaviour is a bit annoying, but
c(1:3)[c(1,NA,3)]
[1] 1 NA 3

Offhand, I suspect that the NAs are in the 8th column.

Hi Elham,
You are not giving us much to go on here.
Show us the commands that (a) confirm there are no NA's in the first column
of z
and (b) output a row of z that has an NA in the first column.
Here's how one might do this:
(a) sum(is.na(z[,1]))
(b) z[ match(TRUE, z[,8] %in% c("11","12","14")), ]
Hi all,
I have a simple problem. I get stuck in using the imported spss data (.sav)
using "read.spss".
I imported data (z) without any problem. After importing, the first column
doesn't contain any "NA". but when I choose a subset of it (like:
z[z[,8]=="11"|z[,8]=="12"|z[,8]=="14",]), lots of NA
9 matches
