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

  • rightward: Increasing order

  • leftward: Decreasing order

  • rightleft: Proceed rightward from i to n, then leftward to 1

  • leftright: Proceed leftward from i to 1, then rightward to n

lode_zigzag(n, i)

lode_rightward(n, i)

lode_leftward(n, i)

lode_rightleft(n, i)

lode_leftright(n, i)

Arguments

n

Numeric, a positive integer
