The getOption()
function in R allows a user to set and examine a range of global options that affect the way R computes and displays its results.
options(…)
getOption(x, default = NULL)
.Options
The getOption()
function takes the following parameter values:
...
: This represents any options that can be defined using name = value
. It can be passed by giving a single unnamed argument which is a named list.Below, we have a list of some options that are used in base R:
Options | result |
---|---|
add.smooth | TRUE |
check.bounds | FALSE |
continue | “+” |
digits | 7 |
echo | TRUE |
encoding | “native.enc” |
expressions | 5000 |
x
: This represents a character string that holds the option name.default
: This is returned if the specified option is not set in the options list.# Implementing the getOption() functiongetOption("add.smooth")getOption("check.bounds")getOption("continue")getOption("digits")getOption("echo")getOption("encoding")getOption("error")
In the code above, we use the getOption()
function to examine certain global options that affect the way R works.
