[R] look up and Missing

[Ashta]

HI  R-Users

Assume that I have a data frame 'temp' with several variables (v1,v2,v3,v4,v5.).

  v1 v2 v3  v4 v5
   1  2   3   3    6
   5  2  4    2    0
   2 -9   5   4    3
   6  2   1   3    4

1, I want to look at the entire row values of when v2 =-9
   like
         2 -9   5   4    3

I wrote
K<- list(if(temp$v2)==-9))

I wrote the like this but  it gave me  which is not correct.
   False false false false false

2. I want assign that values  as missing if   v2 = -9.  (ie., I want
exclude from the analysis

How do I do it  in R?

Thanks in advance
