R package on Nigeria and for Nigeria
# naijR
An R package on Nigeria and for Nigeria
The goal of **naijR** is to make it easier for R users to work with data
related to Nigeria.
## Usage
### Some simple operations
#### Maps
One of the useful aspects of this package is enabling users to plot
country and sub-national geo-spatial maps. Currently, only vector-type
graphics are supported. To find out more, read the vignette–accessible
from within R as follows:
``` r
vignette('nigeria-maps', 'naijR')
```
### Administrative Regions
#### States
To create a list of all the States of the Nigerian Federation, simply
call `states()`.
``` r
library(naijR, quietly = TRUE)
ss <- states()
head(ss)
States
------
- Abia
- Adamawa
- Akwa Ibom
- Anambra
- Bauchi
- Bayelsa
cat(sprintf("\n...but Nigeria has %i States.", length(ss)))
...but Nigeria has 37 States.
```
States from a given geo-political zone can also be selected:
``` r
states(gpz = "ne") # i.e. North-East
States
------
- Adamawa
- Bauchi
- Borno
- Gombe
- Taraba
- Yobe
```
For other capabilities of this function, see `?states()`.
#### Local Government Areas
This is a basic example that shows how to very quickly fetch the names
of Local Government Areas within a given State:
``` r
lgas("Imo")
LGAs
----
- Aboh Mbaise
- Ahiazu Mbaise
- Ehime Mbano
- Ihitte/Uboma
- Ideato North
- Ideato South
- Ezinihitte-Mbaise
- Isu
- Oguta
- Obowo
- Nwangele
- Njaba
- Ngor Okpala
- Mbaitoli
- Nkwerre
- Orsu
- Orlu
- Onuimo
- Okigwe
- Ohaji/Egbema
- Oru East
- Isiala Mbano
- Ikeduru
- Owerri Municipal
- Owerri West
- Owerri North
- Oru West
```
To list all the LGAs in Nigeria, call the same function without any
parameters:
``` r
n <- length(lgas())
sprintf("Nigeria has a total of %i Local Government Areas", n)
[1] "Nigeria has a total of 774 Local Government Areas"
```
