A typical workflow begins with using the Leontief decomposition in the decompr package.

# load the decompr package
library(decompr)

We will use the example data set.

# load the example data set
data(leather)

and apply the leontief decomposition and post multiply with exports

l <- decomp(inter,
            final,
            countries,
            industries,
            out,
            method = "leontief",
            post = "exports"    )

We can now analyse the l object with the gvc package.

library(gvc)

For instance, using the New Revealed Comparative Advantage (nrca()),

nrca(l)
## [1] 1.2676927 1.0581114 0.1533582 1.0087530 1.3176076 0.3068102 0.8635848
## [8] 0.7080925 1.9843574

or using Importing to Export (i2e()),

i2e(l)
##     country              sector        i2e
