Methods which streamline the descriptive analysis of quantitative
matrices. Matrix columns are samples while rows are features i.e. proteins, genes.
Includes methods for visualization (e.g. Heatmaps, Volcanos, pairwise QQ, Bland-Altman plot),
summary statistics (e.g. CV), data normalization methods (e.g. robustscale). Read function for Progenesis.

Quantitative chemical analysis: calibration and evaluation of results
Statistical evaluation of calibration curves
by different regression techniques: ordinary, weighted,
robust (up to 4th order polynomial).
Log-log and Box-Cox transform, estimation of
optimal power and weighting scheme. Tests for heteroscedascity
and normality of residuals. Different kinds of plots
commonly used in illustrating calibrations. Easy "inverse
prediction" of concentration by given responses
and statistical evaluation of results (comparison of
precision and accuracy by common tests).

Functions to manipulate dates and count days for quantitative finance analysis. The 'quantdates' package considers leap, holidays and business days for relevant calendars in a financial context to simplify quantitative finance calculations, consistent with International Swaps and Derivatives Association (ISDA) (2006) <https://www.isda.org/book/2006-isda-definitions/> regulations.
