Arguments

x

an object.

output

character string or a function that determines how the HTML formatted object is shown.

If output is a function, it is called with the path of a (temporary) file with HTML code, e.g. RStudio's viewer function (which is available in the package rstudioapi.

If output equals "stdout", the HTML code is written to the standard output stream (for use e.g. in output produced with knitr), if "file-show", the contents of a file with the HTML code is shown via file.show, and if "browser", the contents of a file with the HTML code is shown by the standard browser (via browseURL).

This arguments has different defaults, depending of the type of the session. In non-interactive sessions, the default is "console", in interactive sessions other than RStudio, it is "browser", in interactive sessions with RStudio it is "file-show".

These default settings can be overriden by the option "html_viewer" (see options).
