r - Error in l$data : $ operator is invalid for atomic vectors shiny app - 


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.

you need provide proper example. rather explaining users have no idea of trying accomplish....please provide input , seps of code lead error. explanation " created in # function @ reactive function...." or saying " # want input in statedatasubset function." users have no idea not helpful.

and, answer error $ operator invalid atomic vectors, self explained. trying use $ access vector. avoid problem change whatever input data.frame. proper solution in code format provided if able explain problem example.
