Pre-built binaries — no Rust compiler required.

```{r installation_1, eval=FALSE}
install.packages("rfastlowess", repos = "https://thisisamirv.r-universe.dev")
```

## From conda-forge

```{r installation_2}
# In a conda environment
# conda install -c conda-forge r-rfastlowess
```

## From Source (GitHub)

Requires [Rust](https://rustup.rs/) and Rtools (Windows).

```{r installation_3, eval=FALSE}
devtools::install_github("thisisamirv/lowess-project", subdir = "bindings/r")
```

---

## System Requirements

- **R**: 4.4.0 or later
- **Windows**: [Rtools](https://cran.r-project.org/bin/windows/Rtools/) —
  required for source installation
- **Rust**: Required for source installation only
  ([rustup.rs](https://rustup.rs/))

On Windows with Rtools, add the MinGW GNU target:

```sh
rustup target add x86_64-pc-windows-gnu
```

## Verifying Installation

```{r installation_4}
library(rfastlowess)

# Fit a simple example
x <- 1:10
y <- x + rnorm(10, sd = 0.5)
model <- Lowess()
result <- fit(model, x, y)
cat("Smoothed values:\n")
print(result$y)
```

```{r session-info}
sessionInfo()
```
