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!
Regards,
Yihui
