How to use plotly in R shiny

Question

I'm attempting to add a graph to the shiny output that I created. I'm receiving a graph generation error. Could someone please look and help. The parameters of the bar graph are computation-based outputs produced by calculations.

renderPlotly(server output$graph)

Plotly (x=c (as.numeric (input$contract), round (frateperton()), differencerate()),

y=c("Contract Rate," "ZBC Rate," "Difference")

"Zero Based Rate Chart" is its name.

("bar" type)

})

UI \splotlyOutput("graph"),
