# ggstance

**Important**: This package has been superseded by [ggplot2 3.3.0](https://www.tidyverse.org/blog/2020/03/ggplot2-3-3-0/), which now has full native support for horizontality. The ggstance package will continue to be maintained for some time, but please consider switching to ggplot2.

## Installation

Get the development version from Github with:

```R
# install.packages("devtools")
devtools::install_github("lionel-/ggstance")
```

## Horizontal geoms

While `coord_flip()` can only flip a plot as a whole, ggstance
provides flipped versions of Geoms, Stats and Positions. This makes it
easier to build horizontal layer or use vertical positioning
(e.g. vertical dodging). Also, horizontal Geoms draw horizontal
legend keys to keep the appearance of your plots consistent.

Horizontal Geoms:

- `geom_barh()`
- `geom_colh()`
- `geom_histogramh()`
- `geom_linerangeh()`
- `geom_pointrangeh()`
- `geom_errorbarh()`
- `geom_crossbarh()`
- `geom_boxploth()`
- `geom_violinh()`

Horizontal Stats:

- `stat_binh()`
- `stat_boxploth()`
- `stat_counth()`
- `stat_xdensity()`
- `stat_summaryh()`

Vertical Positions:

- `position_dodgev()`
- `position_dodge2v()`
- `position_nudgev()`
- `position_fillv()`
- `position_stackv()`
- `position_jitterdodgev()`

## Examples

### Basics ###

To create a horizontal layer in ggplot2 with `coord_flip()`, you have
to supply aesthetics as if they were to be drawn vertically:

```r
library("ggplot2")

# Vertical
ggplot(mpg, aes(class, hwy, fill = factor(cyl))) +
  geom_boxplot()

# Horizontal with coord_flip()
ggplot(mpg, aes(class, hwy, fill = factor(cyl))) +
  geom_boxplot() +
  coord_flip()
```

In ggstance, you supply aesthetics in their natural order:

```r
library("ggstance")

# Horizontal with ggstance
ggplot(mpg, aes(hwy, class, fill = factor(cyl))) +
  geom_boxploth()
```

### Facetting with Free Scales

Some plots are hard to produce with `coord_flip()`. One case is
facetting with free scales. Here is an example from @smouksassi:

```r
library("ggplot2")
library("ggstance")

df <- data.frame(
  Group = factor(rep(1:3, each = 4), labels = c("Drug A", "Drug B", "Control")),
  Subject = factor(rep(1:6, each = 2), labels = c("A", "B", "C", "D", "E", "F")),
  Result = rnorm(12)
)

vertical <- ggplot(df, aes(Subject, Result))+
  geom_boxplot(aes(fill = Group))+
  facet_grid(. ~ Group, scales = "free_x")
vertical
```

How do we flip this plot? With `coord_flip()`, the free scales are not
flipped correctly:

```r
vertical + coord_flip()
vertical + facet_grid(Group ~ ., scales = "free_x") + coord_flip()
```

On the other hand a ggstance horizontal layer will work properly:

```r
horizontal <- ggplot(df, aes(Result, Subject))+
  geom_boxploth(aes(fill = Group))+
  facet_grid(Group ~ ., scales = "free_y")
horizontal
```

### Using vertical positions

In this example we use vertical dodging to align measurements
within subgroups.

```{r}
data <- expand.grid(
  Group = c("A", "B"),
  Subgroup = c("a", "b", "c"),
  y = 1:10
)
data$y <- sample(1:4, replace = TRUE, size = nrow(data))

ggplot(data, aes(y, Group, colour = Subgroup)) +
  stat_sum(position = position_dodgev(height = 0.5))
```
