How to embed my Machine-learning R code in a website - javascript

I need to run my R-code through a website, with the user giving feature values from the website itself, which I have to use as new data for prediction in the R-code. How can I do it?

Have a form on the website which performs an HTML post to a REST api on your web server which will write the information to a database such as MySql, Postgres, MongoDB, or any other database of your choice. Then use a DBMS database management system (DBMS) such as MySQL Workbench, pgAdmin, or Robomongo to query the database and put the data into a csv file, and run your R-code on it. Then use the parameters from your machine-learning model on your server to serve content.

You can expose any R code as a REST API using packages such as plumber, OpenCPU or RestServ. Such an API can then be integrated into the website using Jacascript.

How to retrieve value from MySQL database using Javascript and Microsoft Visual Studio?

Okay so its like this. I am using Microsoft Visual Studios (Javascript/HTML/CSS coding) to create an app which retrieves and sends data into a MySQL database. I setup my MySQL database using MySQL workbench. I created a localhost and connected Visual Studios to the database. It shows the connection on the Server Explorer on the left side of the IDE.
And this is where I get stumped. I don't know how exactly to retrieve the data set inside that database. I've been taught to use Eclipse and phpMyAdmin using a php file to connect, retrieve and store data into the database.
However, I am not familiar with how Visual Studios do their data retrieval. How do I go about this guys?? Basically, I got an HTML file, a CSS file, a Javascript file, I got the MySQL database running and it says I have connection to it on Visual Studios.
The database name is EmployeeCred, and inside the database is a table called employeelogindata with columns of informations.
What should I do?
You'll need to create some sort of API for your JavaScript(frontend) to interact with. You could create a PHP API(backend) which would connect to the database and return JSON data for your frontend. You could then access this using the JavaScript fetch API
Actually, for those still wondering how, Visual Studios has a service for Cordova App which allows for a built-in backend service to the app. Simply go to the Overview panel and look up the backend service feature. Follow the steps and read through the Corodva Documentation available on the internet.

create a digital archive with a database

I'm new to web development and I'm trying to create a website with a database that will store all the files in the archive with the ability to delete files and upload new ones to the database from my web page.
1)I used HTML, CSS, javascript to create the website
2)MySQL to create the database
and I also tried phpMyAdmin to create the database
but where will I go from there?
How will my website control and show the database?
According to your question, I assume that you don't have a backend for your website. You need to have a backend to access the database. You can use php as the backend to connect with the mySQL database.
PS: I can see that you have tagged the question with php. If you are using php and still you can't connect to the database, please share your code snippets.

How to show sqlite data on HTML5

I have a local sqlite database, and a lightweight mini-httpd server on the same linux host.
I'd like to provide web visualization of the data contained on the sqlite database.
I've checked Google Charts and it basically does what I need, but doesn't directly connect to sqlite. Should I feed the data manually with javascript?
What is the best way for showing result of sqlite queries to a web browser?
If you want to show statistic with Google Charts you have to provide the data with a proper format.
You need an app where to make request and connect to the DB running on the webserver, make the query with javascript to that app and then pass the data to G charts.
You have also tons of libraries to show data, all you have to know is the licence your site will be running. jchartfx if really powerfull

Android data transfer between apps and website

It there a way to get data from the website? Is JavaScript possible for this case?
Just a few words to Google for you. Just look out for a REST API for you Server (you can write it in PHP) to give the data in JSON to your app.
Use GSON in your app to get the JSON object to a Java object. And keep in mind to do all network calls in a thread/async task. You can have a look at the Volley library provided by Google.
Have fun with your Project ;) Step by step, and you will get it!
