Preserved seed and possibly set the seed

Usage

rxWithSeed(
  seed,
  code,
  rxseed = rxGetSeed(),
  kind = "default",
  normal.kind = "default",
  sample.kind = "default"
)

rxWithPreserveSeed(code)

Arguments

seed

R seed to use for the session

code

Is the code to evaluate

rxseed

is the rxode2 seed that is being preserved

kind

character or NULL. If kind is a character string, set R's RNG to the kind desired. Use "default" to return to the R default. See ‘Details’ for the interpretation of NULL.

normal.kind

character string or NULL. If it is a character string, set the method of Normal generation. Use "default" to return to the R default. NULL makes no change.

sample.kind

character string or NULL. If it is a character string, set the method of discrete uniform generation (used in sample, for instance). Use "default" to return to the R default. NULL makes no change.

Value

returns whatever the code is returning
