sack2

A collection of miscellaneous useful functions used across projects.

General functions:

• vals to summarize frequency of values in a vector

• count_NA_patterns to return a count of each missingness pattern in data
• count_all to call dplyr::count() on all columns in the dataframe
• cor0 to tidily summarize pairwise correlations

• cross_table to call gmodels::CrossTable() with all proportions suppressed
• pval_to_symbol to convert numeric p values to corresponding significance symbols
• pval_to_jama to convert numeric p values to JAMA format
• replace_NAs_with_medians to replace NAs with medians throughout dataframe
• round0 to round all numeric columns in a dataframe
• fnr_names to find and replace patterns in names of a dataframe
• key to create a random alphanumeric key
