Dear Helpers
 
I have a sample frame and i have sampled from it using three methods and now i want to calculate the statistics but i only get the population parameters.
 
H <- matrix(rnorm(100, mean=50000, sd=5000))
sampleframe=data.frame(type=c(rep("H",100)),value=c(H))
sampleframe
 
str=strata(sampleframe,c("type"),size=c(20,), method="srswor")
sample.strat<-getdata(sampleframe,str)
sample.strat
length(H)
i get: 
 
length(H)
[1] 100

Desire to get:
length(H)
[1] 20
 
Best Regards
