# ggdollar

The goal of ggdollar is to provide a more intuitive way to set `theme()` arguments

when using the package *ggplot2*.

`theme()` is a complex function, we provide nested lists of functions that should

guide the users to what they through a sequence of limited choices thanks to

autocomplete.

It's a draft, but works ok already.

## Installation

``` r

remotes::install_github("moodymudskipper/ggdollar")

```

## Intro

`ggset`, `ggdo` and `ggremove` are nested lists of functions.

`ggset` lets you dig to the element you want to change,

  and apply those changes, so that `ggset$panel$background(fill = "blue")` is the same as

  `theme(panel.background = element_rect(fill = "blue"))`. The arguments are

  most of the time ultimately forwarded to an `element_*()` function and you can

  change many attributes of a component at once. `?margin` will provide the

  description of most parameters.

`ggdo` on the other hands starts from the action you want to perform, For instance

the equivalent to the above would be `ggdo$fill_background$panel("red")`.

  Typically with `ggdo` we set only a single or a couple of attributes at once.

`ggremove` is like `ggset` but helps removing components, it sets the relevant

`theme()` arguments to `element_blank()`, `NULL` or `"none"`.

For instance `ggremove$panel$background()` is the same as `theme(panel.background = element_blank())`

There would have been many other ways to organize these lists and we went for

an partially arbitrary reorganization rather than a fully systematic one.

```{r example}

library(ggdollar)

library(ggplot2) 

ggplot(iris, aes(Sepal.Width, Sepal.Length, color = Species)) + geom_point() + 

  ggset$panel$background(fill = "white", color = "black") + # top down approach to change theme

  ggdo$set_text$angle$axis$x$bottom$text(45) + # bottom up approach

  ggremove$legend$all() # removing element

```

## To do : 

* find better names

* support in `ggdo` attributes that aren't related to `element_*()` functions

* Play around and see what doesn't feel right

* better doc

* cleaner code

* display native *ggplot2* code
