Subject: R random number generator
R 0.64 on windows NT 4.0
Sometimes I got an error message by doing this
> .Random.seed <- c(1, 1:2)
> .Random.seed
[1] 1 1 2
> runif(5)
Warning: Wrong length .Random.seed; forgot initial RNGkind? set to Wichmann-Hill[1] 0.02253721 0.84832584 ........
Sometimes I do not get error message:
> .Random.seed <- c(1, 1:2)
> .Random.seed
[1] 1 1 2
> runif(1)
[1] 0.5641106
>
Not even this got error message sometimes
> .Random.seed <- c(0, 1:2)
> runif(1)
[1] 0.03381877
>
But sometime it does
> .Random.seed <- c(0, 1:2)
> .Random.seed
[1] 1 1 2
> runif(1)
Warning: Wrong length .Random.seed; forgot initial RNGkind? set to Wichmann-Hill
[1] 0.02253721
Notice the result are also different. I cannot seem to pin point
when it gets or not get the error message.
