s[enter image description here][1]server.r df <- read.csv("") output$out1 <- renderui({ params <- colnames(df) # these colum names goes list selectinput.. param_list <- params # dynamically create dropdown box selectinput("params", label = "choose variable observe", choices = param_list) # print(param_list) }) statedatasubset <- reactive({ input$params datasetvariable <- input$params }) i trying use input$param dynamically created in function @ reactive function, not sure why getting error similar code in past has worked. params there in output$out1, want input in statedatasubset function.
