q	number of questions
freq	character string indicating frequency, can be "annually", "quarterly", "monthly". Supports fuzzy unabmigous strings.
start	vector containing year,period
end	vector containing year,period'
seed	for reproducible random number generation
rng	of the categorical scale default 1-3

Examples

# generate survey likerandom sample
srvyData <- generateSamplePanel(500,3,"quarterly",
                                c(1999,1),
                                c(1999,1),
                                weight=round(runif(500,2,80)))


# generate 
grps <- generateRandomGroups(3,1:500,LETTERS)

# merge group information by uid
srvyWgroups <- merge(grps,srvyData,by="uid")

# add some NAs (to simulate item non-response)
# check which cols should be protected from 
# being hit by random NAs
head(srvyWgroups)
randomPanel <- generateRandomNAs(srvyWgroups,c(1,2,3,4),50,1)
