default_na_str {tern}

Default string replacement for NA values

Description

The default string used to represent NA values. This value is used as the default value for the na_str argument throughout the tern package, and printed in place of NA values in output tables. If not specified for each tern function by the user via the na_str argument, or in the R environment options via set_default_na_str(), then NA is used.

Usage

default_na_str()

set_default_na_str(na_str)

Arguments

single string value to set in the R environment options as the default value to replace NAs. Use getOption("tern_default_na_str") to check the current value set in the R environment (defaults to NULL if not set).

Value

• default_na_str returns the current value if an R environment option has been set for "tern_default_na_str", or NA_character_ otherwise.
