option to unzip it (if its a zip file that is).
x must be a valid URL using http or ftp. This function requires that the URL ends
in a filename (unfortunately not all URLs do).
A character vector of the downloaded file. If downloading a zip file with auto_unzip = TRUE, it return a vector of filename(s) where they were unzipped.
Plot a png or jpg image file
wu_popup(x, height = 360, bgcol = "#222")wu_popup(x, height = 360, bgcol = "#222")
x |
A filename or URL of a PNG or JPG image |
height |
The (minimum) height of the viewer pane |
bgcol |

This will display a PNG or JPG image in the RStudio viewer pane.
x can be either a local file or a URL. This gives you the ability to
create 'popup' slides in a R script that you work through during a lesson.
height determines the minimum height in screen pixels that the viewer pane will
resize itself to (if needed). Set to NULL to disable.
bgcol can be a named HTML color (e.g., gray) or a hexadecimal HTML color value (e.g., #FF0034).
