R help - Sep 2009 - SRS Required sample size for simulated data

Hi 
 
Out of curiosity, how can i determine the minimum required sample size of this
data in a combined form say 100 entries which r functions can i use?

 

R helpers
 
Please help me combine the simulated data to a form of table where: Hypermarket
have 10 rows, supermarket have 15 rows,......., spazashops with 35 rows.
 
Hypermarket <- rnorm(10, mean=20000, sd=7000)
Supermarket <- rnorm(15, mean=12000, sd=4000)
Minimarket   <- rnorm(20, mean=10000, sd=4000)
Cornershop  <- rnorm(20, mean= 8000, sd=3000)
Spazashop   <- rnorm(35, mean= 7000, sd=3000)
 
i am trying to write a code to simulate data such that i have 10% of
hypermarkets, 15% of supermarkets,etc.

My guess is that by "table" you are really looking for a
'dataframe'.
Further, I guess that an indexed format is most useful to you.
Try:

# Create the requested dataframe
 dat=data.frame(type=c(rep("Hypermarket",10),rep("Supermarket",15),rep("Minimarket",20),rep("Cornershop",20),rep("Spazashop",35)),
value=c(Hypermarket,Supermarket,Minimarket,Cornershop,Spazashop))#  Print out
first 15 rows. dat[1:15,]R helpersPlease help me combine the simulated data to a
