# orbital 
[](https://github.com/tidymodels/orbital/actions/workflows/R-CMD-check.yaml)

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)
```
