Hello, gmail on aagarw30

Sorry, could you elaborate please. Didn’t quite get that. Ty Abi

Hello, thanks for watching and commenting. Sure can help. Reason for error is addition comma (,) you have in code after the menu item. Either remove that and run or add another menu item underneath. It should run fine after these changes. Hope this would help. If still running issues, pls reach out to me. Ty Abi

Hello, so are you looking to upload a file and make changes and save in the same file and downlod when all changes done ?

Hi im just trying to take input from an excel sheet and overwrite it after editing on Shiny app..

@@charithkrish please try reactiveVal in server side of the code. Use your input file as reactiveVal object. That way any changes made would be retained. Let me know if you are not able to do and I will create a gist . Ty Abi

Yes, you can have loading of packages in global.r

I am sorry. Didn’t get the question. Could you pls elaborate so I can try helping? Ty Abi

Thanks so much for reply and this amazing tutorial@@abhinavagrawal6317 . I am trying to explain the question; I have a cohort of case and a cohort of control with their gene expression data. Now, I want to make correlation matrix for a set of gene for cases and same for the controls for the same set of genes. Now I want to plot them under same x and y axis in one plot of which the upper part of the plot would be for cases and the lower part would be for controls. Thanks

Hello, you need not install Shiny Widgets separately to use widgets like sliderinput or selectinput or others. Once you have shiny package installed and loaded, you can start using the widgets and add them to your code/app. Hope this helps. ty Abi.

@@abhinavagrawal6317 Thank you for your advice sir.

Which R Gui version are you using? Latest versions have "Change Directory" option in the Menu > File option > Change Directory and this can help you change the directory. Hope this helps. Ty Abi.

I figured out the problem, I just use Rstudio to set Directory on my computer.@@abhinavagrawal6317

Hello, your observation on code from global.r is correct. What I coded in for visualisation part in global.r was to demonstrate how a visualisation piece of code can be made dynamic and then used that in server.r. Pls use clean copy of code files from my GitHub in case of any errors. To your point, variables/objects used in global.r is accessible to both ui and server components. Retain only those pieces here which needs to be global/common or expected to be accessed by either of ui or server side components. Ty Abi

Hello, sure. You can increase this limit by setting the shiny. maxRequestSize option prior to starting Shiny. For example, options(shiny. maxRequestSize = size * 1024^2) size can be 5 or 10 or whatever size size say 20MB. Try and let me know. Hope this helps.

Thanks, will do! Have some pipeline and ideas. If anything specific, pls feel free to shoot me an email or comment here. ty Abi.

Have you created a issue in Github? I will try to look into this. Ty Abi.

Sorry, did not get it. You want a custom message to appear in the tool tip? ty Abi.

@@abhinavagrawal6317 At 4:30, in the code, line 62. Instead of return nothing, can you print out a message near the cursor to let the user know that nothing is available?

Like giving multiple choices of download format to the user or how? Kindly elaborate. Ty Abi

@@abhinavagrawal6317 i need to download two plot but its actually an output from arima plot and prophet plot. The arima is fine the file can be opened but the prophet only showed white image. And I made the button separately, still didn't figure out the way for one button for two outputs.

Most welcome!

Difficult to diagnose without seeing what code changes done. If there is any small reproducible which I can use to debug, happy to help. Ty Abi

Do you have an email address so I send a copy of my code so you can debug as I am unable to send files or code here

​@@abhinavagrawal6317 I sent an email to you regarding the issue I complained about. A response would be greatly appreciated. Thanks

@@alfredgagariga1286 let me double check. Don’t remember receiving it. Ty Abi

Hello Faqih, thanks for comments and watching video. Spatial data frame is what is used and will be required. Ty Abi

@@abhinavagrawal6317 my pleasure sir, btw, do you have tutorial about reactive output data frame using click event? i have no idea how to do that, thankyou very much

@@fadhlurrohmanfaqih480 I am so sorry didn’t quite get that. Could you please elaborate requirement with an example what you want and I can give it a shot. Good day! Ty Abi

@@abhinavagrawal6317 Thankyou verymuch for replying my commend sir. So I build a simple project using only one page, in this page there's map, value box and also data frame. So what i trying to do is whenever i clicked in specific area on map, it will trigger the code to showing some value on my value box (this far I success, but I don't know why I cant fill the box with any color, it just showing blank box with icon and value), also, based on information I get from click event, i want to update my data frame which filtered by the value I obtained from click event (for example, when i click on India, it will send the value into filter(Country == Region) where region equal to India, but the data frame that i want to show in this page is different than the data I used to build map, but has same column name). Im wondering if I can stored the value from click event, so i can use it in any output? Thank you

or maybe theres some easy way to fix my problem without store the value into some variabel

you mean more sub menus, something like cascading sub menus? ty Abi.

yes, exactly that@@abhinavagrawal6317

Hello, based on your comment appears that the process aborted in flight. Was there any errors in the deployment process in the console logs? Did this run in the local browser without errors? Ty Abi

@@abhinavagrawal6317 this runs absolutely fine on local browser and without any error. There were no errors when I deployed it. While producing spatial maps in tmap plot, the app got disconnected.

@@manishtanwar8578 hello, well if that is the case will need to debug and check where lies the problem. Do you have a reproducible version of app that I can try run locally and deploy and check from my end ? If so, please share a reproducible version over my gmail at aagarw30 and I will give it a shot .. Ty Abi

Hello Rahul, sure. Did you try running the code from GitHub or you coded in Rstudio local instance? If it is GitHub version then I will re run and test it for error to help you else you will have share code with me to troubleshoot so I can reproduce. Thanks for watching and commenting.

Thanks a lot 😊
