Hi Dr. Kubovy,
Here is my code so far: My question is: how do I then get a frequency
count of Y_Q10A with the WTPP applied to it?
myfile<-("c:/test2.txt")
mysubset<-myfile
mysubset$Y_Q02 <-mysubset$DVSELF <-NULL
mysubset2<-mysubset
mysubset2$Y_Q10B <-mysubset2$GP2_07 <-NULL
myVariableNames<-c("PUMFID","PROV","REGION","GRADE","Y_Q10A","WTPP")
myVariableWidths<-c(5,2,1,2,1,12.4)
mysubset2<-read.fwf(
file=myfile,
width=myVariableWidths,
col.names=myVariableNames,
row.names="PUMFID",
fill=TRUE,
strip.white=TRUE)
print(mysubset2)
happyguys<-subset(mysubset2, PROV==48 & GRADE == 7 & Y_Q10A < 9)
print(happyguys)
df <- data.frame(PROV = rnorm(10), REGION = rnorm(10), GRADE = rnorm
(10), Y_Q10A = rnorm(10), WTTP = rnorm(10))
df1 <- df[, 1:4] * df[, 5]
Thanks,
Nat

The column you were worried about is not part of the data.
You can get a vector of the record ids by
rownames(df)
