proximity() computes two matrices that account for the
similarity between pairs of countries and pairs of products.
Usage
proximity(balassa_index, compute = "both")
Value
A list of two matrices.
Arguments
balassa_index
(Type: dgCMatrix) the output from
balassa_index()) or an equivalent arrangement.
compute
(Type: character) the proximity to compute. By default this is
"both" (both proximity matrices) but it can also be "country"
or "product".
Details
The current implementation follows
atlas2014economiccomplexity to obtain the likelihood that two
products "p1" and "p2" are exported by the same country and, conversely,
that two countries "c1" and "c2" export the same product.
