Error in eval: object 'mydata' not found

Dear all,

Hope you can help me fix the following error:

Error in eval: object 'mydata' not found

Before building the webpage and running the server function, I define 'mydata':

mydata=read.csv('mydata.csv',sep='\t')

However, somehow this error occurs. I think it is related to the fact that, within the server function of Rshiny, I am trying to predict a model (mymodel) that was fitted with mydata, as below. Perhaps mydata should be explicitly defined within the server function..?

server <- function(input, output, session) {

    output$plot <- renderPlot(
        width=600,
        height =400,
        {

        ## some irrelevant code I left out ## 

          pred <- predictAll(mymodel, newdata=newdata) 

         ## plotting based on pred ##

           })

Thanks very much for your help!

Best,

Merel

Update: I have added a 'data' folder, such that mydata=read.csv('data/mydata.csv'), and I have added this code within the server function as well.

Yet I still get the error 'mydata not found'. Notably: it works fine when I run it in my console! However, when I clear Renviroment and then runApp(), the error occurs.

Hope someone can help me out with this!
