statebins is an alternative to choropleth maps for US States
The following functions are implemented:
- `statebins` - creates "statebin" charts in the style of <http://bit.ly/statebins> - This version uses discrete `RColorBrewer` scales, binned by the "breaks" parameter.
- `statebins_continuous` - creates "statebin" charts in the style of <http://bit.ly/statebins> - This version uses a continuous scale based on `RColorBrewer` scales (passing in a 6 element `RColorBrewer` palette to `scale_fill_gradientn`).
### TODO
- The current version is usable, but I think the plot margins and the legends need work
- Apply algorithm to switch to light-on-dark depending on the background tile color
### News
- Version `1.0.0` released
### Installation
``` {.r}
devtools::install_github("hrbrmstr/statebins")
```
### Usage
All of the following examples use the [WaPo data](http://www.washingtonpost.com/wp-srv/special/business/states-most-threatened-by-trade/states.csv?cache=1). It looks like the colums they use are scaled data and I didn't take the time to figure out what they did, so the final figure just mimics their output (including the non-annotated legend).
``` {.r}
library(statebins)
# current verison
packageVersion("statebins")
```
## [1] '1.0'
``` {.r}
# the original wapo data
dat <- read.csv("http://www.washingtonpost.com/wp-srv/special/business/states-most-threatened-by-trade/states.csv?cache=1", stringsAsFactors=FALSE)
gg <- statebins(dat, "state", "avgshare94_00", breaks=4,
labels=c("0-1", "1-2", "2-3", "3-4"),
legend_title="Share of workforce with jobs lost or threatened by trade", font_size=3,
brewer_pal="Blues", text_color="black",
plot_title="1994-2000", title_position="bottom")
gg
```
![plot of chunk unnamed-chunk-3](./_README_files/figure-markdown_github/unnamed-chunk-31.png)
``` {.r}
# continuous scale, legend on top
gg2 <- statebins_continuous(dat, "state", "avgshare01_07",
