Default string replacement for NA values

Source: R/utils_rtables.R

[Stable]

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.

default_na_str()

set_default_na_str(na_str)

Arguments

na_str

(string)
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.

  • set_default_na_str has no return value.

Functions

  • default_na_str(): Accessor for default NA value replacement string.

  • set_default_na_str(): Setter for default NA value replacement string. Sets the option "tern_default_na_str" within the R environment.
