xportr_options: Get or set xportr options

In xportr: Utilities to Output CDISC SDTM/ADaM XPT Files

Get or set xportr options

Description

There are two mechanisms for working with options for xportr. One is the options() function, which is part of base R, and the other is the xportr_options() function, which is in the xportr package. The reason for these two mechanisms is has to do with legacy code and scoping.

The options() function sets options globally, for the duration of the R process. The getOption() function retrieves the value of an option. All xportr related options of this type are prefixed with "xportr.".

Usage

xportr_options(...)

Arguments

...	Options to set, with the form name = value or a character vector of option names.

Options with options()

xportr.df_domain_name

defaults to "dataset"
The name of the domain "name" column in dataset metadata.

xportr.df_label

defaults to "label"
The column noting the dataset label in dataset metadata.

xportr.domain_name

defaults to "dataset"
The name of the domain "name" column in variable metadata.

xportr.variable_name

defaults to "variable"
The name of the variable "name" in variable metadata.

xportr.type_name

defaults to "type"
The name of the variable type column in variable metadata.

xportr.label

defaults to "label"
The name of the variable label column in variable metadata.

xportr.length

defaults to "length"
The name of the variable length column in variable metadata.

xportr.order_name

defaults to "order"
The name of the variable order column in variable metadata.

xportr.format_name

defaults to "format"
The name of the variable format column in variable metadata.

xportr.format_verbose

defaults to "none"
The default argument for the 'verbose' argument for xportr_format.

xportr.label_verbose

defaults to "none"
The default argument for the 'verbose' argument for xportr_label.

xportr.length_verbose

defaults to "none"
The default argument for the 'verbose' argument for xportr_length.

xportr.type_verbose

defaults to "label"
The default argument for the 'verbose' argument for xportr_type.

xportr.character_types

defaults to "character"
The default character vector used to explicitly coerce R classes to character XPT types.

xportr.character_metadata_types

defaults to c("character", "char", "text", "date", "posixct", "posixt", "datetime", "time", "partialdate", "partialtime", "partialdatetime", "incompletedatetime", "durationdatetime", "intervaldatetime")
The default character vector used to explicitly coerce R classes to character XPT types.

xportr.numeric_metadata_types

defaults to c("integer", "numeric", "num", "float")
The default character vector used to explicitly coerce R classes to numeric XPT types.

xportr.numeric_types

defaults to c("integer", "float", "numeric", "posixct", "posixt", "time", "date", "hms")
The default character vector used to explicitly coerce R classes to numeric XPT types.

Options with xportr_options()

Alternative to the options(), the xportr_options() function can be used to set the options. The xportr_options() function also returns the current options when a character vector of the options keys are passed into it. If nothing is passed into it, it returns the state of all xportr options.

Examples

xportr_options("xportr.df_label")
xportr_options(xportr.df_label = "data_label", xportr.label = "custom_label")
xportr_options(c("xportr.label", "xportr.df_label"))
xportr_options()
