Datasets for use in designing surveys in Sierra Leone # sierraleone: Datasets for use in designing surveys in Sierra Leone 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. ## Installation The `sierraleone` packages is not yet released on CRAN. The development version of the package can be installed from GitHub with: ``` r if(!require(remotes)) install.packages("remotes") remotes::install_github("spatialworks/sierraleone") ``` ## Usage 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: ``` r library(rgdal) library(rgeos) library(raster) ``` ### Province borders The Sierra Leone province borders `SpatialPolygonsDataFrame` is accessed via the `province` dataset. ``` r sierraleone::province #> class : SpatialPolygonsDataFrame #> features : 4 #> extent : -13.30901, -10.27056, 6.923379, 9.999253 (xmin, xmax, ymin, ymax) #> crs : +proj=longlat +datum=WGS84 +no_defs +ellps=WGS84 +towgs84=0,0,0 #> variables : 13 #> names : OBJECTID, admin1Name, admin1Pcod, admin1RefN, admin1AltN, admin1Al_1, admin0Name, admin0Pcod, date, validOn, validTo, Shape_Leng, Shape_Area #> min values : 1, Eastern, SL01, Eastern, NA, NA, Sierra Leone, SL, 2016/08/01, 2016/10/17, NA, 1.8390606275, 0.0563871543411 #> max values : 4, Western, SL04, Western, NA, NA, Sierra Leone, SL, 2016/08/01, 2016/10/17, NA, 12.645889079, …
