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.
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:
vignette('nigeria-maps', 'naijR')
To create a list of all the States of the Nigerian Federation, simply call states()
.
library(naijR, quietly = TRUE) ss <- states() head(ss) cat(sprintf("\n...but Nigeria has %i States.", length(ss)))
States from a given geo-political zone can also be selected:
states(gpz = "ne") # i.e. North-East
For other capabilities of this function, see ?states()
.
This is a basic example that shows how to very quickly fetch the names of Local Government Areas within a given State:
lgas("Imo")
To list all the LGAs in Nigeria, call the same function without any parameters:
n <- length(lgas()) sprintf("Nigeria has a total of %i Local Government Areas", n)
Want to create a function to check how many LGAs a particular State has?
how_many_lgas <- function(state) { n <- length(lgas(state)) cat(state, "State has", n, "LGAs\n") } how_many_lgas("Sokoto")
It is common to come across datasets where phone numbers are wrongly entered or misinterpreted by software like MS Excel. The function fix_mobile()
helps with this.
fix_mobile("8032000000")
The function works on vectors; thus an entire column of a table with phone numbers can be quickly processed. Illegible or irreparable numbers are turned into missing values, e.g.
(dat <- data.frame( serialno = 1:8, phone = c( "123456789", "0123456789", "8000000001", "9012345678", "07098765432", "08123456789", "09064321987", "O8055577889" ) ))
fix_mobile(dat$phone)
To download and install the current stable version of this package from CRAN:
