Description Usage Arguments Value Author(s) See Also Examples
The refactor_list
command is a helper function for
refactor
. It prints the R
code requiqred for a
'lookup' to the console, for inclusion in data preparation/cleaning scripts
(perhaps after a bit of editing!).
For vary large lookups, it might make more sense to pass the lookup to
refactor
using a file. You can write the lookup
to a .csv
file by supplying a path/name to the the file
argument.
To try and make the process less laborious, refactor_list
also has a
consolidate
parameter. If set to TRUE
, the lookup generated
will pass the 'TO' values through consolidate_values
,
hopefully consoldating factor levels which are different for small
formatting reasons in to one. See the consolidate_values
documentation for details.
For a demonstration of how refactor
and refactor_list
work together, see the package vignette, with:
vignette('brocks')
1 | refactor_list(x, consolidate = FALSE, file = NULL)
|
x |
A |
consolidate |
|
file |
A writable file path. If supplied, the lookup will be written
out to a two column .csv file, as opposed to written to the console. The
file produced can be passed to the file argument in |
Nothing. Prints to the console/terminal with cat
.
