Source: R/get_vars_by_pattern.R
get_vars_by_pattern.Rd

This function searches for specific variable names (columns) across multiple data frames in the global environment that match a certain naming pattern.

Usage

get_vars_by_pattern(data_pattern = NULL, var_pattern = NULL)

Arguments

data_pattern

A string containing a regular expression to match the names of the datasets in the global environment. For more information on supported regular expressions, see R's regex documentation.

var_pattern

A string containing a regular expression to match the variable names within those datasets.

Value

A named list where each element name is a dataset and the value is a character vector of matching variable names. Returns NULL if no datasets match.

Examples

if (FALSE) { # \dontrun{
# Load package data into global environment
data("fake_snacn_ph_fu")
data("fake_snacn_ph_wave3")

# Search for variables starting with "ph" in SNAC-N physical datasets
get_vars_by_pattern(data_pattern = "^fake_snacn_ph", var_pattern = "^ph")
} # }
