rPoisDS serverside assign function

Description

primary serverside assign function called by ds.rPois

Usage

rPoisDS(n, lambda = 1)

Arguments

n

length of the pseudorandom number vector to be generated as specified by the argument <samp.size> in the function ds.rPois

lambda

a numeric scalar specifying the expected count of the Poisson distribution used to generate the random counts. Specified directly by the lambda argument in ds.rPois. May be a scalar or a vector allowing lambda to vary from observation to observation.

Details

Generates the vector of pseudorandom numbers (non-negative integers) from a Poisson distribution in each data source as specified by the arguments of ds.rPois. This serverside function is effectively the same as the function rpois() in native R and its arguments are the same.

Value

Writes the pseudorandom number vector with the characteristics specified in the function call as a new serverside vector on the data source on which it has been called. Also returns key information to the clientside: the random seed as specified by you in each source + (if requested) the full 626 length random seed vector this generated in each source (see info for the argument <return.full.seed.as.set>). It also returns a vector reporting the length of the pseudorandom vector created in each source.
