This function takes a data frame representing travel between origins
(with origin codes in name_orig
, typically the 1st column)
and destinations
(with destination codes in name_dest
, typically the second column) and returns a matrix
with cell values (from attrib
, the third column by default) representing travel between
origins and destinations.
od_to_odmatrix(x, attrib = 3, name_orig = 1, name_dest = 2)
A data frame representing flows between origin and destinations
A number or character string representing the column containing the attribute data
of interest from the flow
data frame
A number or character string representing the zone of origin
A number or character string representing the zone of destination
