# tagger

<!-- badges: start -->
<!-- badges: end -->

The goal of tagger is to easily add tags to facetted plots in order to identify panles. 

## Installation

<!-- You can install the released version of tagger from [CRAN](https://CRAN.R-project.org) with: -->

<!-- ``` r -->
<!-- install.packages("tagger") -->
<!-- ``` -->

You can install the development version from [GitHub](https://github.com/) with:

``` r
# install.packages("devtools")
devtools::install_github("eliocamp/tagger")
```
## Example

In the default usage, you can simply add `tag_facets()` to add a tag to each panel of a ggplo2 plot.

```{r example}
library(tagger)
library(ggplot2)

ggplot(mtcars, aes(hp, mpg)) +
   geom_point() +
   facet_grid(cyl ~ vs) +
   tag_facets()
```
If you want to tag rows and columns instead of each panel indivdually, you can set it with the `tag` argument. 

```{r}
ggplot(mtcars, aes(hp, mpg)) +
   geom_point() +
   facet_grid(cyl ~ vs) +
   tag_facets(tag = "rc")
```
