mlr stats1 and stats2 now support a -s feature in which means, linear regressions, etc. evolve record-by-record as new records appear over time. This is particularly useful in tail -f contexts. See also http://johnkerl.org/miller/doc/reference.html#stats1 and http://johnkerl.org/miller/doc/reference.html#stats2.mlr filter now supports a -x flag to negate the sense of the filter: instead of editing logic expressions e.g. from mlr filter '$x < 10 || $x > 20' to mlr filter '$x >= 10 && $x <= 20', you can simply do mlr filter -x '$x < 10 || $x > 20'. See also http://johnkerl.org/miller/doc/reference.html#filter.- In the event a CSV file lacks header lines, you can use
mlr --implicit-csv-header to add positional header 1,2,3,.... You can also convert those to desired text using mlr label. See also http://johnkerl.org/miller/doc/reference.html#label.
- Heterogeneity support is improved for
sort, stats1, stats2, step, head, tail, top, sample, uniq, and count-distinct. See also #79.
mlr stats2 now has a logistic-regression feature, but I recommend treating it as experimental until some numerical-stability issues involving my naïve Newton-Raphson solver are worked out -- namely, it doesn't converge in all cases.
