Project Description: Using R language, Shiny package, and R-studio, develop a simple web app that does the following: - Load a file containing a MxN matrix (comma delimited) into a data table. The first row of the matrix holds the column names. The first column holds the row names. Remainder values are floating point numbers. - Display this data table that hold the matrix. - When the user click on a row of the data table, graph this row onto chart. As the user click on more rows, plot more line graphs (correspond to each clicked row) onto this same chart. Label each line graph with its row name. Each line will have its own color. Note that “parallel coordinates plot” technique will be needed to graph multiple rows on the same chart. - When the user click on a row (in the displayed data table) that has already been graphed, remove the line graph for that row. Similarly, if a user click on a line graph on the chart, remove that line graph. - Provide a slide bar so the user can adjust the X scale of the line graph. Deliverables: Using R-studio (down load from [login to view URL]) create a “ui.R” and “server.R” files to implement the above. Create a test file holding a 101x201 (101 rows by 201 columns) matrix, where the element of the first row hold column names c1, c2, … c200. And the first column holds the row names, r1, r2, …r100. Fill the remainder of the matrix elements with random floating point numbers.

Hello, I'm a PhD student working with R language on the daily bases. Please have a look on my resent shiny-r project (under development) [login to view URL] I will be happy to learn more and work on your project. Would you like to run it only on your computer or also online? The only issue I see that the budget is a bit too small. As I understood you are doing it as assignment for the school? Thus I would set the price to $70 net revenue from the project. Thanks Vova [login to view URL]

Hi, I'm Matt and would like to help you (scripting in R for 3 years). UPDATE: based on added requirements and additional work needed for slider, color and 10 line graph limitation more work will be needed yet the bid is still discounted (10 output hours at $20 would be $200). I understand your project and see it's doable. Please tell me if you need uploading anywhere to see both scripts working (Shiny can be installed on Linux - don't have one installation currently, otherwise was a Linux/Unix system administrator for 6 years - and on Mac). I'll definitely plan to have a working solution created, tested and optimized on my MacBook Pro. Currently I have to finish two small projects yet can start working on this over weekend. I'm incorporated so cannot lower the bid amount - it's already lowered since I would like to have more projects done here with R and because it's a challenge with Shiny involvement. Looking forward to your reply, Matt

Hi, I can have your Shinny App running in less than 3 days. On your project description you mentioned that you need to upload a MxN matrix while in your deliverables you mention an 101x201 matrix. Do you need the matrix dimension to be flexible? Also, in the deliverables you mention to "Fill the remainder of the matrix elements with random floating point numbers". Do you need to include an option that will generate a random matrix or this will be the way you want to deal with NAs? Anything is doable, I just wanted to be clear on the goals of the app. Looking forward to hear from you. Arturo
