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)
