%description
A collection of fast (utility) functions for data analysis. Column and row
wise means, medians, variances, minimums, maximums, many t, F and G-square
tests, many regressions (normal, logistic, Poisson), are some of the many
fast functions. References: a) Tsagris M., Papadakis M. (2018). Taking R
