These options will be used on objects of class 'data.frame'.

Usage

opts_data.frame(
  constructor = c("data.frame", "read.table", "next", "list"),
  ...
)

Arguments

constructor

String. Name of the function used to construct the environment, see Details section.

...

Should not be used. Forces passing arguments by name.

Value

An object of class <constructive_options/constructive_options_data.frame>

Details

Depending on constructor, we construct the object as follows:

  • "data.frame" (default): Wrap the column definitions in a data.frame() call. If some columns are lists or data frames, we wrap the column definitions in tibble::tibble(). then use as.data.frame().

  • "read.table" : We build the object using read.table() if possible, or fall back to data.frame().

  • "next" : Use the constructor for the next supported class. Call .class2() on the object to see in which order the methods will be tried.

  • "list" : Use list() and treat the class as a regular attribute.
