time_ordered_coords | R Documentation |
time_ordered_coords()
is a helper function to create time-ordered DAGs.
Pass the results to the coords
argument of dagify()
. If .vars
if not
specified, these coordinates will be determined automatically. If you want to
be specific, you can also use a list or data frame. The default is to assume
you want variables to go from left to right in order by time. Variables are
spread along the y-axis using a simple algorithm to stack them. You can also
work along the y-axis by setting direction = "y"
.
time_ordered_coords(
.vars = NULL,
time_points = NULL,
direction = c("x", "y"),
auto_sort_direction = c("right", "left")
)
.vars |
A list of character vectors, where each vector represents a single time period. Alternatively, a data frame where the first column is the variable name and the second column is the time period. |
time_points |
A vector of time points. Default is |
direction |
A character string indicating the axis along which the variables should be time-ordered. Either "x" or "y". Default is "x". |
auto_sort_direction |
If |
A tibble with three columns: name
, x
, and y
.
