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.
Arguments
- flow
A data frame representing flows between origin and destinations
- attrib
A number or character string representing the column containing the attribute data of interest from the
flowdata frame- name_orig
A number or character string representing the zone of origin
- name_dest
A number or character string representing the zone of destination
