expand_rownames: expand parameter descriptions in rownamesMove rownames that describe parameters (e.g. xi[2009]) to columns.
expand_rownames(x, time_name, geo_name, group_names)
| x | A table with rownames in the format |
|---|---|
| time_name | A name for any resulting time variable. |
| geo_name | A name for any resulting geographic variable. |
| group_names | Names for any resulting group variables. |
x with additional columns (see details).
It should rarely be necessary to call expand_rownames directly. But
elements extracted from dgirtfit-class objects may have
rownames of the format param[group1__groupK,t] for parameters indexed
by group and time period, or param[t] for parameters indexed by time
period. expand_rownames moves this information to columns whose names
are given by the col_names argument. The rownames in their original
format will appear in another column called rn.
