Convenience functions for RGL HTML layouts

The asRow function arranges objects in a row in the display; the getWidgetId function extracts the HTML element ID from an HTML widget.

asRow(..., last = NA, height = NULL, colsize = 1)
getWidgetId(widget)

Arguments

...

Either a single "combineWidgets" object produced by asRow or a %>% pipe of RGL objects, or several objects intended for rearrangement.

last

If not NA, the number of objects from ... that are to be arranged in a row. Earlier ones will remain in a column.

height

An optional height for the resulting row. This is normally specified in pixels, but will be rescaled as necessary to fit the display.

colsize

A vector of relative widths for the columns in the row.

widget

A single HTML widget from which to extract the HTML element ID.

Details

Using asRow requires that the manipulateWidget package is installed.

asRow produces a "combineWidgets" object which is a single column whose last element is another "combineWidgets" object which is a single row.

If n objects are given as input and last is given a value less than n, the first n - last objects will be displayed in a column above the row containing the last objects.

Value

asRow returns a single "combineWidgets" object suitable for display or nesting within a more complicated display.

getWidgetId returns a character string containing the HTML element ID of the widget.
