# schemeR

[![Project Status: WIP - Initial development is in progress, but there has not yet been a stable, usable release suitable for the public.](http://www.repostatus.org/badges/latest/wip.svg)](http://www.repostatus.org/#wip)

The goal of schemeR is to visualize SQLite databases.

## Installation

You can install schemeR from github with:

```{r gh-installation, eval = FALSE}

# install.packages("devtools")

devtools::install_github("jsta/schemeR")

```

## Usage

This is a basic example:

### SQLite 

```{r example, results = 'hide'}

library(schemeR)

db <- dplyr::lahman_sqlite()

res <- schemeR::render_sqlite(db)

schemeR::export_svg(res, "images/sqlite_example.png")

```

![](images/sqlite_example.png)

### data.frame

```{r message=FALSE, results='hide'}

df <- data.frame(

          "name" = 1:4,

          "people" = c("bob", "jim", "beatrice", "ann"))

res <- schemeR::render_df(df)

schemeR::export_svg(res, "images/df_example.png")

```
