shinylight.call: JavaScript function

In shinylight: Web Interface to 'R' Functions

JavaScript function

Description

Calls a server function as defined in the server's call to the slServer function.

Arguments

fn	string The name of the R function to call.
data	object An object whose keys are the arguments to the function being called.
plotElement	string, HTMLElement If provided, the <img> element (or id of the element) that will receive the plot output (if any). The plot returned will be the size that this element already has, so ensure that it is styled in a way that it has the correct size even if no image (or an old image) has been set.
extra	object [optional] An object whose keys can be: "imgType": Type of image required, "png" (default) or "svg"; "info": Function to be called if the R function sendInfoText is called; "progress": Function to be called if the R function sendProgress is called.

Value

Result object that might have a plot property (giving a string that would work as the src attribute of an img element, representing graphics drawn by the command), a data property (giving the value returned by the command) and a headers property (giving the column names in the data returned if any). If the promise resolves to an error, the argument to the error function is a string representing the cause of the error.
