This guide provides a basic overview of the use of the csodata package for new users. Install (if necessary) and load the package:

# # Install or update the package:

library(csodata)

Table of Contents

A list of all the table available on the cso StatBank can be downloaded with cso_get_toc. You can search throught the title field using cso_search_toc. (A “Loaded cached toc” or “Loaded cached data” message indicates that the data was retrieved from the cache, instead of being downloaded again.)

toc <- cso_get_toc()

Downloading Data

To download a dataset, use cso_get_data.

tbl1 <- cso_get_data("PEA19")
#> Loaded cached data

Metadata can be also downloaded or displayed to console:

meta1 <- cso_get_meta("CDP06")
#> Loaded cached data
cso_disp_meta("CDP06")

Geographic Data

Geographic vector data in ESRI shapefile format can be downloaded for use in mapping. This uses the older 2011 data, which includes demographic information. Newer maps, including the revisions to the NUTS regions made in 2016, is also available.

shp <- cso_get_geo("NUTS3_2011")
#> Loaded cached data

This data can be plotted using the tmap package. Here we plot the 2011 population, which is included as the “TOTAL2011” column in the map data.

# install.packages("tmap")
library(tmap)

t <- tm_shape(shp) +
       tm_fill(col="TOTAL2011", 
                    palette = viridisLite::viridis(20),
                    style="cont", legend.reverse = TRUE,
                    title = "Population 2011") +
       tm_borders(col = "black") +
       tm_layout(frame = FALSE, scale = 1.3)
