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

    # load the decompr package
    library(decompr)

    ## Please consider citing R and decompr,
    ## using citation()
    ## citation('decompr')

We will use the example data set.

    # load the example data set
    data(leather)
    attach(leather)

and apply the leontief decomposition and post multiply with exports

    l <- decomp(x = inter,
                y = final,
                k = countries,
                i = industries,
                o = out,
                method = "leontief",
                post = "exports"    )

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

    library(gvc)

    ## Please consider citing R and gvc,
    ## citation()
    ## citation('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
    ## 1 Argentina         Agriculture  3.404712
    ## 2 Argentina Textile_and_Leather  6.443233
    ## 3 Argentina Transport_Equipment  0.762098
    ## 4    Turkey         Agriculture  7.467932
    ## 5    Turkey Textile_and_Leather 11.125843
    ## 6    Turkey Transport_Equipment  2.544472
    ## 7   Germany         Agriculture  5.632133
    ## 8   Germany Textile_and_Leather  5.280111
    ## 9   Germany Transport_Equipment 25.397173
