Sample code:
selectInput(inputId = "sampleDataset", label = "Choose Dataset", choices = c('boston', 'auto_mpg', 'red_wine'), selected = "boston") data_preloaded <- reactive({ get(input$sampleDataset) }) var_name <- data_preloaded() #> not working
im confused about your intentions. to choose datasets or variables form within a dataset?
also if var_name <- data_preloaded() is just a one liner in your server code, then it would only execute once, and not be reactive, what is the intention ?
var_name <- data_preloaded()
