These functions control the order of lodes within strata in an alluvial
diagram. They are invoked by stat_alluvium()
and can be passed to
the lode.guidance
parameter.

Numeric, a positive integer
Numeric, a positive integer at most n
Each function orders the numbers 1 through n
, starting at index
i
. The choice of function made in stat_alluvium()
determines the order in which the other axes contribute to the sorting of
lodes within each index axis. After starting at i
, the functions order
the remaining axes as follows:
zigzag
: Zigzag outward from i
, starting in the outward direction
zigzag
: Zigzag outward from i
, starting in the inward direction
forward
: Increasing order (alias rightward
)
backward
: Decreasing order (alias leftward
)
frontback
: Proceed forward from i
to n
, then backward to 1
(alias rightleft
)
backfront
: Proceed backward from i
to 1, then forward to n
(alias leftright
)
