R4VN_examples: R4VN Example Cookbook

In R4VN: Health Data Analysis and Publication-Ready Reporting

R4VN Example Cookbook

Description

A central index of practical examples. The detailed examples are also merged into the individual help pages, so use ?labvar, ?tab, ?ttest, ?ranksum, and the corresponding command name while working.

Data workflow

usedf() sets active data. opendata() and savedata() import and export. appenddata() stacks observations; mergedata() joins by keys. keepvar(), dropvar(), ordervar(), renvar(), genvar(), replacevar(), and labvar() edit active or explicit data.

Statistical workflow

tab1() and sum1() provide quick console checks, including nested by stratification. describe() shows active-data structure. tab() and tabmulti() produce publication tables. ttest() includes one-sample, independent, and paired t tests. ranksum(), signrank(), kwallis(), and friedman() provide the principal nonparametric tests. swilk() assesses normality. corr(), regress(), logistic(), and poisson() provide correlation and regression models. tabsurv() and tabmeta() provide complete one-command survival and meta-analysis reports; their help pages contain scenario-based cookbooks.

Graph workflow

gbar(), ghist(), gbox(), gscatter(), gline(), gdensity(), and gpie(), gforest(), and groc() use base graphics and return reusable r4vn_graph objects.
