Report correlations, regressions and summaries

Functions to create publication-ready tables for common analysis tasks

report_cat_vars()

Create a summary table for categorical variables and their relationship with a continuous outcome variable

report_cor_table()

Calculate correlation matrices

It can be surprisingly difficult to calculate correlation matrices, particularly when data is weighted or incomplete. These functions help and prepare data for report_cor_table()

cor_matrix()

Calculate correlation matrix with significance tests and descriptives

cor_matrix_mi()

Create a (weighted) correlation matrix from multiply imputed data

wtd_cor_matrix_mi()

Create a correlation matrix from multiply imputed data with weights

pcor_matrix()

Calculates a partial correlation matrix controlling for one or more variables

svy_cor_matrix()

Create a correlation matrix from survey data with summary statistics

tidy(<cor_matrix>)

Tidy a correlation matrix

tidy(<svy_cor_matrix>)

Tidy a survey-weighted correlation matrix

Formatters and reporting helpers

Functions to format numbers for statistical reporting and other helpers for statistical reporting

fmt_ci()

Format confidence interval based on the bounds

fmt_cor()

Format number as correlation coefficient

fmt_p()

Format p-value in line with APA standard (no leading 0)

fmt_pct()

Format fraction as percentage string

round_()

Round function that returns trailing zeroes

round_df()

Round all numeric columns in dataframe

sigstars()

Significance stars for p-values

get_pairwise_letters()

Make and assess scales

Psychologists often use multiple items to measure a construct. These functions create scale scores and assess reliability (internal consistency)

make_scale()
