try this:
temp.new <- temp[temp$v2 != -9, ]
temp.new
I hope it helps.

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
