This repository contains the source of [R for Data Science](http://r4ds.hadley.nz) book.
The book is built using [Quarto](https://quarto.org/).

The R packages used in this book can be installed via

```{r}
devtools::install_github("hadley/r4ds")
```

## Images

### Omnigraffle drawings

-   Font: 12pt Guardian Sans Condensed / Ubuntu mono

-   Export as 300 dpi png.

-   Website font is 18 px = 13.5 pt, so scale dpi to match font sizes: 270 = 300 \* 12 / 13.5.
    (I also verified this empirically by screenshotting.)

    ``` r
    #| echo: FALSE
    #| out.width: NULL
    knitr::include_graphics("diagrams/transform.png", dpi = 270)
    ```

### Screenshots

-   Make sure you're using a light theme.
    For small interface elements (eg. toolbars), zoom in twice.

-   Screenshot with Cmd + Shift + 4.

-   Don't need to set dpi:

    ``` r
    #| echo: FALSE
    #| out.width: NULL
    knitr::include_graphics("screenshots/rstudio-wg.png")
    ```

### O'Reilly

To generate book for O'Reilly, build the book then:

```{r}
devtools::load_all("../minibook/"); process_book()

html <- list.files("oreilly", pattern = "[.]html$", full.names = TRUE)
file.copy(html, "../r-for-data-science-2e/", overwrite = TRUE)
```
