Stat Tools for End Users

Description

Basic and custom statistical tools designed with end users in mind. Functions have optimized defaults, produce decluttered and informative output that is self-explanatory, and generate publication-ready results in 1 line of code.

Basic Stats (improved)

• lm2: like lm(), with robust SE and much more informative output

• t.test2: like t.test(), decluttered, and more informative output

• table2: like table(), showing variable names, and with proportions & chi2 built in

• desc_var: Descriptive statistics for variables (optional, by group(s))

Custom tools from papers by Uri Simonsohn

• twolines: Two-lines test for U-shapes (Simonsohn 2018)

• interprobe: Probe and visualize nonlinear interactions (Simonsohn 2024; Montealegre & Simonsohn 2026)

Graphing

• scatter.gam: Makes scatter plot for x & y, with fitted GAM line y=f(x)

• plot_cdf: Plot empirical cumulative distribution functions (optional, by group)

• plot_density: Plot density functions (optional, by group)

• plot_freq: Plot frequency of observed values (optional, by group)

• plot_means: Barplot of means with confidence intervals and (optionally) tests

• plot_gam: Plot fitted GAM values for a focal predictor

Formatting

• format_pvalue: Format p-values for display

• var_labels: Get/set variable labels (as base-R "label" attributes)

• message2: Print colored messages to console

• resize_images: Resize images (SVG, PDF, EPS, JPG, PNG, etc.) to PNG with specified width

Miscellaneous

• clear: Clear environment, console, and all graphics devices

• list2: Like list(), but unnamed objects are automatically named

• convert_to_sql: Convert CSV files to SQL INSERT statements

• text2: like text() adding text-alignment and background color
