R Shiny reactive subset data - ERROR object of type 'closure' is not subsettable

Question

I\'m trying to make a reactive data subset to avoid doing the subsetting at each stage of the analysis. However I get the error object of type \'closure\' is not sub

Answer 1

Found question was re-asked and answered at https://groups.google.com/forum/#!msg/shiny-discuss/p2eElm-XaqQ/y3vB4l3tt3EJ

Basically, they suggested

data_user <- reactive({ 
    df <- subset(data_all, data_all$consumername %in% input$user)
    df$date <- as.Date(data_user$date)
    df
})

Not enough rep to add a comment, and I thought this would be useful for others - it was for me.
