flatWIOD(wiot, rows = seq_len(dim(wiot)[1]),
  columns = seq_len(dim(wiot)[2]))

Arguments

wiot	WIOD data.table returned by loadWIOD
rows	wiot's rows to be dropped (a numeric vector with negative numbers) or kept (a numeric vector with positive) prior to flattening/reshaping; default: all rows kept
columns	wiot's columns to be dropped (a numeric vector with negative numbers) or kept (a numeric vector with positive) prior to flattening/reshaping; default: all columns kept

Value

ExpSectorNr

Exporting sector -- WIOD numeric codes for industries (integer vector), see also sectors

ExpCountry

Exporting country -- a three-letter ISO country code, as in the WIOD file (character vector), see also countries

value

An absolute value of the flow (in US dollars as in the WIOD source file)

ImpSectorNr
