# eulerr
[](https://github.com/jolars/eulerr/actions)
[](https://app.codecov.io/gh/jolars/eulerr)
[](https://cran.r-project.org/package=eulerr)
**eulerr** generates area-proportional Euler diagrams that display set
relationships (intersections, unions, and disjoints) with circles or ellipses.
[Euler diagrams](https://en.wikipedia.org/wiki/Euler_diagram) are Venn
diagrams without the requirement that all set interactions be present (whether
they are empty or not), which means that, depending on input, **eulerr**
sometimes produces Venn diagrams and sometimes not.
With three or more sets intersecting, exact Euler diagrams are often
impossible. For such cases **eulerr** attempts to provide a good
approximation by numerically tuning the parameters of the ellipses or circles
to minimize the error in the resulting diagram. Residuals and goodness of fit
statistics are provided to assess whether the resulting diagram can be trusted.
## Installation
### CRAN version
```{r install_cran, eval = FALSE}
install.packages("eulerr")
```
### Development version
```{r install_github, eval = FALSE}
devtools::install_github("jolars/eulerr")
```
### Shiny app
eulerr is also available as a shiny app hosted at
[eulerr.co](https://eulerr.co).
## Usage
```{r specification}
library(eulerr)
# From Wilkinson 2012
fit <- euler(
c(
"A" = 4, "B" = 6, "C" = 3, "D" = 2, "E" = 7, "F" = 3,
"A&B" = 2, "A&F" = 2, "B&C" = 2, "B&D" = 1,
"B&F" = 2, "C&D" = 1, "D&E" = 1, "E&F" = 1,
"A&B&F" = 1, "B&C&D" = 1
),
shape = "ellipse"
)
```
We can inspect the goodness-of-fit metrics *diagError* and *stress*
for the solution,
```{r}
fit$stress
fit$diagError
```
and plot it
```{r plot_method}
plot(fit)
```
