I'm not quite sure I understood the second queston but does this work?
subset(temp, xx$v2==-9)
subset(temp, xx$v2!= -9)

Dear Ashta,
Is this what you want?
x <- read.table(textConnection("v1 v2 v3 v4 v5
1 2 3 36
5 2 420
2 -9 5 43
6 2 1 34"), header = TRUE)
closeAllConnections()
x
# Option 1
x1 <- x # copy of x just for this example
x1$v2[which(x1$v2 == -9)] <- NA
x
try this:
temp.new <- temp[temp$v2 != -9, ]
temp.new
I hope it helps.
Best,
Dimitris

1, I want to look at the entire row values of when v2 =-9
Here is how to find out which rows contain -9 and then you can do with
it as you please:
> x
v1 v2 v3 v4 v5
1 1 2 3 3 6
2 5 2 4 2 0
3 2 -9 5 4 3
4 6 2 1 3 4
