Basic vector logic not working

I am interning in a computer science lab and I'm very new to R. The language basics are clear, but this particular problem isn't: I have a very large dataframe called "data" which holds data from Halo matches. I'm trying to analyze a certain window such that data$deaths>20 and data$deaths<=27. When I enter the line kills = data$kills[data$deaths>20] or any single condition, it selects the region I want. However, when I input kills = data$kills[data$deaths>20 && data$deaths<=27] "kills" becomes the entire vector data$kills, without selecting any specific region. This is a simple problem, but I can't find anything wrong. How could I fix it?
Maybe something like ... # example data d = data.frame(age=1:20, names=letters[1:20]) # 1. subset using [ d[d$age>10 & d$age<16,] # 2. subset using subset function subset(d,d$age>10 & d$age<16) HTH Pete -- View this message in context: http://r.789695.n4.nabble.com/Basic-vector-logic-not-working-tp3656465p3656594.html Sent from the R help mailing list archive at Nabble.com.
