This is a short vignette which explains some functions in COINr for extracting results from the coin. Once the coin is fully built, up to the point of aggregation, an immediate task is to see what the main results are. In composite indicators, the main starting point is often the ranking of units based on the highest level of aggregation, i.e. the index.
While the aggregated data set (the data set created by
Aggregate()) has all the aggregate scores in it, it
requires a little manipulation to see it in an easy to read format. To
help with this, the get_results() function
library(COINr)
# build full example coin
coin <- build_example_coin(quietly = TRUE)
# get results table
df_results <- get_results(coin, dset = "Aggregated", tab_type = "Aggs")
head(df_results)

highest level of aggregation (here, the index), and with the the columns
arranged so that the highest level of aggregation is first, working down
to lower levels. The function has several arguments, including
also_get (names of further columns to attach to the table,
such as groups, denominators), tab_type (controlling which
columns to output), use (whether to show scores or ranks),
and order_by (which column to use to sort the table).
A useful feature is to return ranks of units inside groups. For example, rather than returning scores we can return ranks within GDP per capita groups:
# get results table
df_results <- get_results(coin, dset = "Aggregated", tab_type = "Aggs", use_group = "GDPpc_group", use = "groupranks")
# see first few entries in "XL" group
head(df_results[df_results$GDPpc_group == "XL", ])

#> 19 6 6 10Another function of interest zooms in on a single unit. The
get_unit_summary() function returns a summary of a units
scores and ranks at specified levels. Typically we can use this to look
at a unit’s index scores and scores for the aggregates:
get_unit_summary(coin, usel = "IND", Levels = c(4,3,2), dset = "Aggregated")
#> Code Name Score Rank
#> 1 Index Sustainable Connectivity 39.79 45
#> 2 Conn Connectivity 28.60 44
#> 3 Sust Sustainability 50.99 43

#> 10 Social Social 22.74 51
#> 11 SusEcFin Economic and Financial (Sus) 54.88 36This is a summary for “IND” (India) at levels 4 (index), 3 (sub-index) and 2 (pillar). It shows the score and rank.
A final function here is get_str_weak(). This gives the
“strengths and weaknesses” of a unit, in terms of its indicators with
the highest and lowest ranks. This can be particularly useful in
“country profiles”, for example.
get_str_weak(coin, dset = "Raw", usel = "ESP")

#> 5 43 99.30 PercentThe default output is five strengths and five weaknesses. The
direction of the indicators is adjusted - see the
adjust_direction parameter. A number of other parameters
can also be adjusted which help to guide the tables to give sensible
values, for example excluding indicators with binary values. See the
function documentation for more details.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
