### Overview

The 'ggRtsy' package works with 'ggplot2' to add an additional color palette to the user’s repertoire. This is the `goghColors` dataset, which contains the RGB and hex codes of colors picked from Van Gogh paintings. It has been broken down into an easy-to-use color palette based on Van Gogh's most famous paintings, in the `gogh_palettes_pop` list. 

#### Functions within the package:

It also has a function that work alongside ggplot to create more interesting data visualizations and add contextual information to the user’s plots. 

- RectangleFiller() - divides data visualizations into a specified number of colored quadrants based on the number of input colors, improving the readability of graphs. 

- scale_color_gogh() - used to color the point/lines of your ggplot

- scale_fill_gogh() - used to fill the inner color/bars of your ggplot

- rgbToHeX() - used to convert rgb color codes to hex color codes

- gogh_interpolate() - interpolates between the colors in `gogh_palettes_pop`

### Usage example

```{r, include=FALSE}

# Hidden chunk because it is setup for example

library(dplyr)

library(ggplot2)

library(ggRtsy)

library(purrr)

exampleData <- starwars %>%

  filter(mass < 1000)

plotExample <- ggplot(exampleData, aes(x = height, y = mass)) +

  geom_point() +

  scale_x_continuous()

```

Using Hex Codes from the dataset `goghColors`, three colors were added on top of a ggplot() sample scatter plot. Based on the plot, the function automatically calculated three equal widths of the rectangles, and stretched them to upper and lower bounds on the y-axis. 

```{r ex1, warning=FALSE}

RectangleFiller(plotExample, c("#e32636", "#9966cc", "#f4c2c2"))

```

#### Continuous scale_color_gogh() example using the `cafeTerrace` color palette:

```{r ex2, warning=FALSE, message=FALSE}

ggplot(exampleData, aes(x = height, y = mass, color = birth_year)) +

  geom_point(size = 3) +

  scale_color_gogh(palette = "cafeTerrace", discrete = FALSE, reverse = TRUE) +

  theme_minimal()

```

#### Discrete scale_fill_gogh() example using the `almondBlossoms` color palette:

```{r ex3, warning=FALSE, message=FALSE}

ggplot(storms, aes(x = category, fill = status)) +

  geom_bar() +

  scale_fill_gogh(palette = "almondBlossoms", discrete = TRUE, reverse = FALSE) +

  theme_minimal()

```

This package also comes with rgbToHex(), converting rgb colors into hex code colors.

```{r}

rgbToHex(c("(225, 104, 39)", "(60, 90, 202)"))

```

### Installation instructions

Get the development version from GitHub:

```{r, message=FALSE, eval=FALSE}

# Install remotes if needed:

# install.packages("remotes")

remotes::install_github("katelyndiaz/ggRtsy")

```

And load it with

```{r}

library(ggRtsy)

```
