Well, you need to find some variable to use for subsetting the data.
Can you share an example of your data?
Would something like the following work for you?
stateID <- c("AL","AK","AR","CA","DE","FL","GA","MN","WA","WI","WY")
var1 <- c(0,0,0,0,0,0,0,0,0,2,0)
df <- data.frame(stateID,var1)
statesWanted <- c("MN","WI")
subsettedDataFrame <- df[df$stateID %in% statesWanted,]
