Is there an alternative, vectored way to write the to_array function?

Suppose we have a ragged, nested sequence like the following: import numpy as np x = np.ones((10, 20)) y = np.zeros((10, 20)) a = [[0, x], [y, 1]] and want to create a full numpy array that broadcasts the ragged sub-sequences (to match the maximum dimension of any other sub-sequence, in this case (10,20)) where […]

How does Backtracking work in this Sudoku solver? How is the next “path” chosen

I have this solve function. From my understanding the backtracking part of this algorithm is the line after the recursive solve(). I would think that it would leave 0’s in the final board. Say if I get to a spot on the board where it needs to backtrack, wont it assign grid[y][x] = 0 then […]

Remove missing data state ‘%’ when using TraMineR’s seqpcplot() function

I am trying to conduct event sequence analysis on longitudinal survey data. I want to create a plot which looks like this (pg. 43 of https://lives-nccr.ch/sites/default/files/pdf/publication/ritschard-shp-life-events.pdf), which I believe was generated using the seqpcplot() function within TraMineR: This would allow me to identify common occupational states which participants transition through whilst in the survey (e.g. […]

There isn’t an option to do this in the jsonedit() function, but the underlying javascript object has an .expandAll() method which should do it. How do I call this method from R […]
