Hi,The problem arises when I lazyLoad() the .Random.seed from a previously saved database. To simplify the process of reproducing the problem, see the example below: ## this assignment may not really make sense, but illustrates the problem delayedAssign('.Random.seed', 1L) typeof(.Random.seed) # [1] "integer" rnorm(1) # Error in rnorm(1) : # .Random.seed is not an integer vector but of type 'promise' typeof(.Random.seed) # [1] "integer" So there must be an "attribute" "promise" somewhere attached to .Random.seed, and I cannot find it. The R function typeof() does not reveal it, but the TYPEOF() function in src/main/RNG.c says it is a 'promise'. My question is, how to make R use the real value of .Random.seed instead of complaining about the promise? Thanks!
Siple answer: Don't creat the promise in the first place, i.e. don't use delayedAssign. What is the real context where this arises? Knowing that may help us decide whether the internals should address this possibility. Best, luke
