als-statistics/lib/table/transpose.js

A powerful and lightweight JavaScript library for descriptive statistics, regression, clustering, outlier detection, and noise analysis using a flexible table/column architecture.

function transpose(table, { n, columns, filtered, isFiltered }) {
   let $columns = Object.values(columns).map(col => col.type === Number ? col.values : null)
   let j = 0;
   for (let i = 0; i < n; i++) {
      if (isFiltered && filtered[i]) continue
      table.addColumn(j, $columns.map(values => values[j]))
      j++
   }
   return table
}

module.exports = transpose
