Dynamically select element from a list and work with it - Shiny R

Question

I have a list of items and I want to use that list in my Shiny R dashboard. I'm trying to select an element from the list and work with it or apply some function like lm on it. Is that possible?

Follow these steps:

• Import the data into R
• Check if the list of elements is in fata.frame format, if not convert it into it.
• To dynamically select elements use selectInput function.
• To dynamically use the table, use the function renderTable.

Something like this:

ui.R

box(
     selectInput("ip_name", "Select input:", choices = names(l))

server.R

Element <- reactive({
    input$ip_name
  })
 output$table <- renderTable({
      data.frame(l[[input$ip_name]])
    })
