Flowcharts that belong in the analysis pipeline

The Gmisc R package's flowchart() function has been improved to support reproducible, code-generated research diagrams such as CONSORT charts, cohort derivation flows, data validation pipelines, and longitudinal follow-up diagrams. Unlike drawing tools, these flowcharts live inside the analysis pipeline — counts update automatically, exclusions stay in sync with the analysis script, and figures survive multiple reviewer rounds without manual editing. The post walks through several practical examples with full R code, covering grouped treatment arms, side exclusion branches, dotted return arrows for censored participants, and custom box shapes for data engineering workflows. The update targets Gmisc 3.4.0.

stick function for the EDA in time series

A new stick function (Seasonal, Trend, Irregular Contribution Kit) has been added to the greybox package for both R and Python. Based on Hans Levenbach's STI classification, it uses ANOVA to quantify the strength of seasonal, trend, and irregular components in a time series. Applied to the classic AirPassengers dataset, it reveals that trend accounts for ~86% of variability. The function supports multiple seasonal components and may be extended to include external regressors in the future.
