## rng.rs
This is a simple Rust program that demonstrates random number generation that is identical to the default behavior of the R programming language.
This code is still very experimental, and it's on my to-do list to convert the embedded `rnorm.rs` module to a standalone crate.
The library exposes these functions:
- `runif` for a uniform distribution.
- `rnorm` for a normal distribution.
- `r_set_seed()` to set the random seed.
In Rust:
```rust
r_set_seed(42);
println!("rnorm: {:.5?}", rnorm(Some(5), 0.0, 1.0));
```
```
rnorm: [1.37096, -0.56470, 0.36313, 0.63286, 0.40427]
```
The equivalent code in R:
``` R
set.seed(42); rnorm(5)
```
```
[1] 1.3709584 -0.5646982 0.3631284 0.6328626 0.4042683
```
