The goal of orbital is to enable running predictions of tidymodels [workflows](https://workflows.tidymodels.org/) inside databases.

## Installation

To install it, use:

``` r
install.packages("orbital")
```

You can install the development version of orbital from [GitHub](https://github.com/) with:

``` r
# install.packages("devtools")
devtools::install_github("tidymodels/orbital")
```

## Example

Given a fitted workflow

```{r}
#| message: false
library(tidymodels)

rec_spec <- recipe(mpg ~ ., data = mtcars) |>
step_normalize(all_numeric_predictors())

lm_spec <- linear_reg()

wf_spec <- workflow(rec_spec, lm_spec)

wf_fit <- fit(wf_spec, mtcars)
```

You can predict with it like normal.

```{r}
predict(wf_fit, mtcars)
```

We can get the same results by first creating an orbital object

```{r}
library(orbital)
orbital_obj <- orbital(wf_fit)
orbital_obj
```

and then "predicting" with it using `predict()` to get the same results

```{r}
predict(orbital_obj, as_tibble(mtcars))
```

you can also predict in most SQL databases

```{r}
library(DBI)
library(RSQLite)

con <- dbConnect(SQLite(), path = ":memory:")
db_mtcars <- copy_to(con, mtcars)

predict(orbital_obj, db_mtcars)
```

and spark databases

```{r}
library(sparklyr)
sc <- spark_connect(master = "local")

sc_mtcars <- copy_to(sc, mtcars, overwrite = TRUE)

predict(orbital_obj, sc_mtcars)
```
