问题 I'm trying to make an interactive chart that plots financial stock data on a shiny app. My attempt is to update continuously the data, hence the chart. I managed this using a package called Highcharter. Below it's shown a part of code in the server part (getDataIntraday() receive two input and returns updated xts). getID <- reactive({ invalidateLater(60000) y <- getDataIntraDay(input$text, input$radio) return(y) }) output$plot1 <- renderHighchart({ y <- getID() highchart() %>% hc_credits

问题 I have a table of data MegaP2 with Organ type, separated into Lung and Skin , and then various cell types all of which come from either lung or skin. I have tried to make the available choices in the Cell Lines dropdown box reflect only those that come from the selected Organ in the first dropdown box. If I select Skin or Lung it gives the relevant cell lines perfectly, but then if I try to select the other organ type it then further restricts the cell lines to only those in both organs

问题 I have the following code. I want to take the input of a valid stock symbol and render a candlestick plot. I want to give the user the option to switch between 20, 50, and 200 day simple moving averages on the plot as well.

问题 I am trying to figure out as I select input in UI to immediately reflect the results on page. My search results led me to look into reactive expression and reactive values. But as I am trying to filter the value on data, I think it is causing some complication yet I have no clue what I am supposed to do with this. It seems like the filter function doesn't seem to work though. This is the error message: Warning: Error in UseMethod: no applicable method for 'filter_' applied to an object of

问题 I'm running a R shiny application on an open source shiny-server, using Ubuntu and NGINX. However, my app keeps getting the message "Disconnected from the Server" for some reason and I can't seem to get it to work. The shiny app runs perfectly fine on my local. I've tried the javascript workaround via the following suggestion in Shiny server session time out doesn't work, but it still doesn't seem to work. Also tried to set app_idle_timeout and app_init_timeout to a longer duration, but to no
