Designing surveys require relevant datasets to be used as basis for sample size calculations, sampling design, survey planning/logistics and survey implementation. These include datasets on population, lists of sampling clusters, map datasets for spatial sampling, and previous survey datasets that can be used for estimating indicator variance and design effects. This package contains relevant datasets for use in designing surveys in Sierra Leone.
The sierraleone packages is not yet released on
CRAN. The development version of the
package can be installed from
GitHub with:
if(!require(remotes)) install.packages("remotes")
remotes::install_github("spatialworks/sierraleone")When installing sierraleone, geospatial packages on which
sierraleone depends on are installed. To use sierraleone package, it
will be important to load these package dependencies that have been
installed. This can be done by:
library(rgdal)
library(rgeos)
library(raster)The Sierra Leone province borders SpatialPolygonsDataFrame is accessed
via the province dataset.
