mixingmatrix complains about the attr '' (empty) in the background

[martinamorris]

The console shows the following error when the Network Descriptives tab is selected:

The code it refers to is this:

statnetWeb/inst/shiny/statnetWeb/server.R

Lines 2458 to 2468 in dd1f1cd

	output$mixmxchooser <- renderUI({
	selectInput('mixmx', label='Choose attribute',
	choices = menuattr())
	})
	outputOptions(output,'mixmxchooser',suspendWhenHidden=FALSE)
	output$mixingmatrix <- renderPrint({
	if(!is.network(nw())) {return()}
	if(!is.null(input$mixmx)){
	mixingmatrix(nw(), input$mixmx)}
	})

If IIUC, the menuattr is a cleaned list of attributes that excludes "vertex.names" and "na":

statnetWeb/inst/shiny/statnetWeb/server.R

Lines 500 to 510 in dd1f1cd

	#don't allow "na" or "vertex.names" as vertex attributes in menus on fit tab
	menuattr <- reactive({
	menuattr <- attrib()
	if(is.element("na",menuattr)){
	menuattr <- menuattr[-which("na"==menuattr)]
	}
	if(is.element("vertex.names",menuattr)){
	menuattr <- menuattr[-which("vertex.names"==menuattr)]
	}
	menuattr
	})

So I'm not sure what the problem is.

@mbojan if you have any ideas, pls lmk, thx.

Done. I think this was a relict from before we made mixingmatrix() stricter by making it err if provided with a non-existent network attribute.

@mbojan THANK YOU!!!
