doGRAS.long: Do the GRAS algorithm for a "long" data.table
In zauster/riot: A package for functions related to input-output tables (IOTs)

Description Usage Arguments Value Author(s) References

This function calculates an updated "long" data.table, based on a data.table dt, which meets the given row and columns totals. Note: dt can contain negative elements.

1	doGRAS.long(dt, rowcol, colcol, rowsum, colsum, ...)

`dt`	the "long" data.table
`rowcol`	the column which holds the row-dimension of the reshaped matrix
`colcol`	the column which holds the column-dimension of the reshaped matrix
`rowsum`	vector with the row totals
`colsum`	vector with the column totals
`...`	parameter to be passed to doGRAS

the updated data.table in the same format as before
