This reproducible R Markdown analysis was created with workflowr (version 1.6.2). The Checks tab describes the reproducibility checks that were applied when the results were created. The Past versions tab lists the development history.
Great! Since the R Markdown file has been committed to the Git repository, you know the exact version of the code that produced these results.
Great job! The global environment was empty. Objects defined in the global environment can affect the analysis in your R Markdown file in unknown ways. For reproduciblity it’s best to always run the code in an empty environment.
The command set.seed(20200629) was run prior to running the code in the R Markdown file. Setting a seed ensures that any results that rely on randomness, e.g. subsampling or permutations, are reproducible.
Great job! Recording the operating system, R version, and package versions is critical for reproducibility.
Nice! There were no cached chunks for this analysis, so you can be confident that you successfully produced the results during this run.
Great job! Using relative paths to the files within your workflowr project makes it easier to run your code on other machines.
Great! You are using Git for version control. Tracking code development and connecting the code version to the results is critical for reproducibility.
The results in this page were generated with repository version 448b94c. See the Past versions tab to see a history of the changes made to the R Markdown and HTML files.
Note that you need to be careful to ensure that all relevant files for the analysis have been committed to Git prior to generating the results (you can use wflow_publish or wflow_git_commit). workflowr only checks the R Markdown file, but you know if there are other scripts or data files that it depends on. Below is the status of the Git repository when the results were generated:
Ignored files:
Ignored: .Rhistory
Ignored: .Rproj.user/
Untracked files:
Untracked: data/ViEWS/
Note that any generated files, e.g. HTML, png, CSS, etc., are not included in this status report because it is ok for generated content to have uncommitted changes.
These are the previous versions of the repository in which changes were made to the R Markdown (analysis/merge.Rmd) and HTML (docs/merge.html) files. If you’ve configured a remote Git repository (see ?wflow_git_remote), click on the hyperlinks in the table below to view the files as they were in that past version.

This page shows how to merge Geo-PKO data with conflict data and visualise the results. The examples used here are Uppsala University’s ViEWS project, which forecasts conflict risk, and the Uppsala Conflict Data Programme (UCDP), one of the world’s leading sources of data on armed conflict. Merging these datasets can provide insights into the links between conflict risk and peacekeeping deployments, and help policymakers make effective peacekeeping decisions where the risk of conflict is high.

We’re using the published Geo-PKO dataset, and conflict forecast data from ViEWS for state-based conflict, non-state conflict, and one-sided violence over the next 36 months in Africa. Both datasets offer insights into the sub-national level, using a unique “PRIO-grid” identifier. The PRIO-grid is an innovative geospatial unit from the Peace Research Institute Oslo that divides the world into roughly 100km x 100km squares, allowing geographic analysis beyond the country level to be streamlined.

The predictor database begins with July 2020 and forecasts the risk of conflict over the next 36 months ahead. Here’s a preview of the data within it, showing state-based (sb), non-state (ns) and one-sided violence (os) forecasts. The variable month_id codes months differently to the Geo-PKO dataset, with every month assigned a different numeric value.

The Geo-PKO dataset we’re working with includes data from previous years, but for this visualisation, we will only use the latest year (July 2019 - June 2020). First, we need to filter the data to include only that period. This way we’ll be looking at deployment status against projected conflict risk from the end of that period until three years from that period. You’ll see both the Geo-PKO and ViEWS datasets include the PRIO-grid identification variable (pg_id or PRIOID), which corresponds to a specific grid square on the map. This is what we’ll use to merge the datasets. In addition to filtering for the time period we want, we will also calculate the average number of troops deployed over that time period.
# filtering for troop deployments over Jul 2019 - Jun 2020
geopko2 <- geopko %>%
select(Mission, year, month, PRIOID, No.troops, country, location, latitude, longitude) %>%
filter(year==2019 & month>6 | year==2020 & month<7)
geopko2$No.troops <- as.numeric(geopko2$No.troops)
# calculating an average number of troops
geopko3 <- geopko2 %>%
group_by(PRIOID) %>%
dplyr::mutate(No.troops = mean(No.troops, na.rm=TRUE)) %>%
ungroup() %>%
filter (! duplicated(No.troops))
geopko3$No.troops <- round(geopko3$No.troops)Here, we also calculate the average conflict risk (state-based, non-state, and one-sided) for each location.
predictors2 <- predictors %>%
group_by(pg_id) %>%
dplyr::mutate(average_allwthematic_sb = mean(average_allwthematic_sb, na.rm=TRUE)) %>%
dplyr::mutate(average_allwthematic_ns = mean(average_allwthematic_ns, na.rm=TRUE)) %>%
dplyr::mutate(average_allwthematic_os = mean(average_allwthematic_os, na.rm=TRUE)) %>%
filter (! duplicated(average_allwthematic_sb))Finally, we merge the two datasets.
# merging geopko with conflict forecast data
geopko3$pg_id <- geopko3$PRIOID
priogriddf <- full_join(
geopko3, predictors2,
by = c("pg_id"),
na.rm = TRUE)Like we mentioned before, the PRIO-grid unit involves dividing the entire world into roughly 100km x 100km squares. That means that if we want to map it, we’ll be working with large files, so keep that in mind when you’re reading in the shapefile:
shapefile <- rgdal::readOGR("data/ViEWS/priogrid.geojson")OGR data source with driver: GeoJSON
Source: "C:\Users\Nguyen Ha\Documents\DPCR\GeoPKO\Pages\GeoPKO\data\ViEWS\priogrid.geojson", layer: "priogrid"
with 64818 features
It has 1 fieldsThe shapefile contains both geospatial polygon data and numerical data that corresponds to the ViEWS dataset; specifically, a PRIO-grid ID and a country ID. Here’s what the non-spatial data looks like, showing five rows in the dataset.
kable(shapefile@data[101:106,]) %>% kable_styling() %>%
scroll_box(width = "100%", height = "200px")| x |
|---|
| 54217 |
| 54218 |
| 54219 |
| 54220 |
| 54221 |
| 54222 |
To work with the data within this shapefile, we need to fortify the shapefile. We also convert the IDs to rownames to make it easier to work with. And, finally, we merge it with pgnewdf2, which we created earlier.
# fortify
shapefile@data$id <- rownames(shapefile@data)
shapefile.df <- fortify(shapefile, region = "id")
# merge data of interest
shapefile.df <- merge(shapefile, priogriddf, by.x = "pg_id", by.y = "pg_id", all.x=F, all.y=T, duplicateGeoms=TRUE)So now shapefile.df has the new attributes, including variables from both Geo-PKO and ViEWS. id is a variable that ties the ‘polygon’, or a single square on the grid, to its location on the map

To map the data, we’re going to use the leaflet package (and a bunch of others to support it). The first thing we do is set up our colour palette and bins. We’re using the ‘viridis’ colour palette, designed for accessibility and continuous-scale representation. The other thing we include is a small segment of code that fixes spacing between any NA value in the legend, and the remainder of the legend, making it easier to see.
bins <- c(0, 10, 20, 50, 100, 200, 500, 1000, Inf)
pal <- colorNumeric("viridis", NULL)
#to fix spacing of NA in legend
css_fix <- "div.info.legend.leaflet-control br {clear: both;}" # CSS to correct spacing
html_fix <- htmltools::tags$style(type = "text/css", css_fix) # Convert CSS to HTMLNext, let’s map. We include three colour layers to shade squares according to their conflict forecast value. These layers cover state-based conflict, non-state conflict, and one-sided violence. Simple markers show where troops are deployed. Troop deployment numbers are included as labels, which you can see for each square on hover.

mapAnd here we have it: an interactive map to view recent peacekeeping deployments (2019-2020) and projected conflict risk over the next 36 months. Extensions of this visualisation can be even more useful, particularly with a time-slider that can help us identify how the risk of conflict changes given peacekeeping deployments (and vice versa). That might be a project for the future.
Another useful dataset is from the Uppsala Conflict Data Programme, which offers insights into deaths from armed conflict. Looking at this data in conjunction with peacekeeping data can be useful to draw conclusions into peacekeeping given the severity of armed conflict, or lack thereof. How to merge with this dataset, and a few examples, will be added soon.
