* **Advanced transformations**: Fast row/column arithmetic (by reference), (grouped) replacing
and sweeping out of statistics (by reference), (grouped, weighted) scaling/standardizing and
(higher-dimensional) between and within/centering transformations.
(higher-dimensional) between/averaging and within/centering transformations.

* **Advanced time-computations**: Fast and flexible indexed time series and panel data classes, (sequences of) lags/leads,
differences and (compound) growth rates on (irregular) time series and panels. Autocorrelation functions for panel data
and panel to array conversions.

Optimized R code ensures minimal overheads. <!-- , but imports C/C++ functions from *fixest*, *weights*, *RcppArmadillo*, and *RcppEigen* for certain statistical tasks. -->
