Display data by mimetype, with optional alternative representations.

Source: R/display.r

publish_mimebundle calls the function stored as option value of jupyter.base_display_func, clear_output calls the value of option jupyter.clear_output_func. (see: IRdisplay-options)

publish_mimebundle(data, metadata = NULL)

clear_output(wait = TRUE)

Arguments

data

A named list mapping mimetypes to content (character or raw vectors)

metadata

A named list mapping mimetypes to named lists of metadata, e.g. list('image/png' = list(width = 5))

wait

Wait to clear the output until new output is available. Default TRUE. If FALSE, clears the existing output immediately before the new output is displayed.

Functions

  • clear_output: Clear the output from the current cell.

Examples

if (FALSE) ## (Run inside of an IRkernel)
publish_mimebundle(list('text/html' = '<h1>Hi!</h1>'))
publish_mimebundle(
  list('image/svg+xml' = '<svg xmlns="http://www.w3.org/2000/svg"><circle r="100"/></svg>'),
  list('image/svg+xml' = list(width = 100, height = 100)))
