Workflow plan data frame, similar to one produced by
Named list with wildcards as names and vectors of
as values. This is a way to evaluate multiple wildcards at once.
Character scalar denoting a wildcard placeholder.
Vector of values to replace the wildcard
in the drake instructions. Will be treated as a character vector.
Must be the same length as
Logical, whether to rename the targets
based on the values supplied for the wildcards
Logical, whether to add columns that trace the wildcard expansion process. These new columns indicate which targets were evaluated and with which wildcards.
Character vector of names of columns to look for and evaluate the wildcards.
Character scalar, separator for the names
of the new targets generated. For example, in
A workflow plan data frame with the wildcards evaluated.
The commands in workflow plan data frames can have
wildcard symbols that can stand for datasets, parameters, function
arguments, etc. These wildcards can be evaluated over a set of
possible values using
Specify a single wildcard with the
values arguments. In each command, the text in
wildcard will be replaced by each value in

rules should be a list with wildcards
as names and vectors of possible values as list elements.
