Shiny bindings for embedding

Output and render functions for using embedding() within Shiny applications and interactive R Markdown / Quarto documents.

Usage

embeddingOutput(output_id, width = "100%", height = "480px")

renderEmbedding(expr, env = parent.frame(), quoted = FALSE)

Arguments

output_id

Output variable to read from.

width, height

Element size, passed to htmlwidgets::shinyWidgetOutput().

expr

An expression that generates an embedding() widget.

env

The environment in which to evaluate expr.

quoted

Is expr already quoted? Defaults to FALSE.

Value

embeddingOutput() returns a Shiny output UI element; renderEmbedding() returns a Shiny render function.

Details

In a Shiny app the lasso selection is pushed back to the server as input$<output_id>_selected, a 0-based integer vector of the selected rows (so embeddingOutput("umap") populates input$umap_selected). It updates on every completed selection and is NULL until the first one.
