how to call variable defined in reactive function of shiny in other reactive function

I have following server.r file in Shiny

 enterdata <- reactive({
     a <- "Hello"
     b <- data.frame()

 })

How would I call variable a in other reactive function. I have dataframe as weell in enterdata,but I want only a to be called in other function

 getdata <- reactive({

    sum <- paste(enterdata()$a,"Neil")

 })

Is the above right way to do it?

You should treat reactive as a function. Therefore if you want to return more then one value put it for example in a list, like here: 

enterdata <- reactive({
    a <- "Hello"
    b <- data.frame()

    list(a = a, b = b)

 })

Later you can just treat it as list:

getdata <- reactive({
    sum <- paste(enterdata()$a,"Neil")
 })
