Is it possible to create a progress bar that displays the information of the amount of data that has been read? (e.g., "Read X% of Z rows")? 回答1: R cannot tell you how many rows are in your data until the initial load is complete (I think). However, you can use the built in Shiny progress bar to give your users a message that the data is loading: x<-list.files() data<-data.frame() withProgress(message = 'Reading Data!', value = 0, { for(i in 1:length(x)){

Here is the JSFiddle below: http://jsfiddle.net/LmuR7/1/ (using plugin from here: http://tympanus.net/codrops/2013/03/29/quotes-rotator/ ) And the extra code added to allow for pause on hover of the content : // Pause on hover in, resume on hover out this.$items.hover(function(){ THIS.paused = true; }, function(){ THIS.paused = false; });` 回答1: The biggest problem is that the progress bar

Could anyone please help me clarify some things? (I first learnt OOP in PHP.) So a class can be made like this: var object = new class(constructparams) { var private_members; // Can be accessed from within the code inside this definition only. this.public_members; // Can be accessed from everywhere. var private_functions = function() {} this.public_functions = function() {} } object.prototype.semi_public

So this would be a "grouped" barchart essentially. I am not able to plot this grouped bar chart using R. The code snippet I am using is below: dataset How do I get this grouped bar chart

I will be using discrete data values, as opposed to randomly generated values as the example on their website . I have tried to play around with the live code example of the Group / Stacked Bar Chart and put in JSON data containing my own values. What I tried to do was take the JSON data from the horizontal bar chart and put it in as the data for the vertical bar chart. This is the data I used on the live code example in place of the data in the Group / Stacked Bar
