Thanks for the report: now fixed. rbinom was only checking if p was unchanged, and not setting up correctly if n changed too.
In version 0.99.0 for Windows NT I get the following:
.Random.seed
[1] 0 21012 4461 28299
rbinom(10,10,.3)
[1] 4 5 5 1 5 2 4 2 6 2
rbinom(10,9,.3)
[1] 0 0 0 0 0 0 0 0 0 0
rbinom(10,10,.3)
[1] 3 3 2 2 3 1 3 3 3 2
rbinom(10,11,.3)
[1] 0 0 0 0 0 0 0 0 0 0 I tried similar inputs in version 0.65.1:
.Random.seed
[1] 0 16049 70 30225
rbinom(10,10,.3)
[1] 3 5 3 1 1 3 3 2 5 1
rbinom(10,11,.3)
[1] 1 3 2 3 4 3 4 2 1 5
rbinom(10,100,.3)
[1] 20 0 0 0 0 0 0 0 0 0
rbinom(10,100,.3)
[1] 0 0 0 0 0 0 0 0 0 0
