Display information about data types that can read() and write() can use, as well as, the original functions that are delegated (see they respective help pages for more info and to know which additional parameters can be used in read() and write()).
data_types(types_only = FALSE, view = TRUE)Arguments
- types_only
If
TRUE, only a vector of types is returned, otherwise, atibblewith full specifications is provided.- view
If
TRUE, the result is "viewed" (displayed in a table in a separate window, if the user interface allows it, e.g., in RStudio) and returned invisibly. Otherwise, the results are returned normally.
Value
An tibble with types_only = FALSE, or a character vector.
Details
The function is mainly designed to be used interactively and to
provide information about file types that can be read() or write(). This
cannot be done through a man page because this list is dynamic and other
packages could add or change entries there. With view = FALSE, the function
can, nevertheless, be also used in a script or a R Markdown/Notebook
document.
Examples
if (FALSE) { # \dontrun{
data_types()
data_types(TRUE)
