QUESTION
I have file txt with format like this
...ANSWER
Answered 2021-Jun-15 at 21:31You add each line to the variable list_Siswa. So for instance the first element of list_Siswa will be ["Nama"," John"], and so data_Siswa[0] equals "Nama" and data_Siswa[1] equals " John". Then data_Siswa[2] throws an error, because there is no such element in the array.
The code isn't smart enough to see Nama: John and assume the following lines are grades that should be associated with John. If you want that, you'll have to do it yourself.
QUESTION
I developed an app using rshiny, https://smandape.shinyapps.io/mmdit/. I am trying to make it WCAG 2.1 accessible. I am using WAVE (Web accessibility evaluation tool) to check for accessibility. Currently, the errors popping are related to 'missing form label'. These errors are specifically for the code fileInput or rabiobuttons (5 errors are on Data import tab). For example, around the following code. WAVE shows the error for the placeholder for fileInput.
...ANSWER
Answered 2021-Jun-15 at 03:54fileInput accessibility was one of the things changed in the Shiny v1.6 release: https://shiny.rstudio.com/reference/shiny/1.6.0/upgrade.html
Closed #2929: Fixed keyboard accessibility for file picker button: keyboard users can now tab to focus on fileInput() widget. (#2937)
Are you definitely using v1.6? It looks like you are, so you may have identified a bug in the shiny framework.
EDIT: I had a look at the code for the fileInput control, and it looks to me like the input and label elements aren't properly linked together. I reported it as an issue: https://github.com/rstudio/shiny/issues/3426
QUESTION
I am creating a shiny app and part of its purpose is to allow the user to upload a CSV and be able to select column/variables of interest. So far, I have successfully managed to upload a file, but the reactive part to select columns does not work, that is when I click on 'incorporate external information' nothing happens. I used this answer for guidance. How can I allow the user to select the columns and then display them accordingly? The purpose of column selection is to then allow the user to perform regression analysis on selected columns.

QUESTION
I am creating a shiny app to allow the user to upload a CSV, select a dependent and independent variable(s) and then perform a regression analysis. So far I have been able to upload the file, and select the columns of interest based on this answer. But the app is not being able to construct the lm model. The purpose is to first generate and display lm results by using the summary and then produce some plots. How can I allow the user to perform a simple regression analysis? The sample file can be downloaded from here.

I am making a shiny app that allows the user to upload a CSV, then select the independent and dependent variables. Right now I am able to upload a file, select variables and run regression analysis. But, I am stuck at the step where I would pass the lm object to autoplot then making it interactive via autoplotly in a new tab. How can I create interactive regression plots via using user selected variables in a shiny app?

QUESTION
I am making a shiny app that allows the user to upload a shapefile using the sf package. When I select the .shp file via the Browse window, I get an error. How can I allow the user to upload a shapefile, that then get it read by st_read' or readOGR. And, I don't know why st_read is going to C:\Users\Ed\AppData... as this is not location of the shapefile.
library(shiny) library(shinydahsboard) library(sf) UI
...ANSWER
Answered 2021-Apr-29 at 08:24ESRI shapefiles are known troublemakers, as they live over multiple files - the single *.shp file is not enough for your shiny app to work with.
Consider a solution proposed by user fiorepalombina on RStudio Community forum: https://community.rstudio.com/t/shinyfiles-and-shapefiles/89099
QUESTION
I have done this code for model updating, something that's related to civil engineering. In the very last line of the code provided I am getting this error (TyperError: only integer scalar .....), could you please tell me what is the problem? I've tried a lot, but not working. I've tried to convert it to an array with integer, float, and also convert it to list, but nothing is wokring Thank you in advance
...ANSWER
Answered 2021-Jun-13 at 14:17you start your loop by defining a running variable 'i'. But all over the loop, you redefine it to be other integers and unrelated objects. Such as in line 83, line 155, and others. It's difficult to understand your intentions from the question. but if I understand correctly, the problem can be solved by changing every 'i' in the loop to a differently named temporary variable. A simpler solution would be to change the 'i' variable at the beginning of the for loop to smth else. I suggest you adopt a habit of using variable names that have meaning and not just single or double letters.
QUESTION
I've reviewed similar posts and haven´t found any that address this specific need. Below is very simple MWE of what I'm trying to do: shown in 2 images, and in runnable code. My "Hide" button (or remove UI) doesn't work. Help!! I'm sure it's a simple solution but I'm new to this.
What I'm trying to do: Click on the "Add" button and a file input prompt appears below. Click "Hide" button and the file input prompt goes away. Click "Add" again (after "Hide") and the file input prompt appears again. If you click "Add" now (and repeatedly), that single file input prompt remains. (Most other posts have the object appearing repeatedly, again and again in a growing column, with every additional click of the button - this isn't what I need). Just one click to make it appear (and clicking "Add" over and over just keeps it there in its original single manifestation), and "Hide" makes it go away. Simple as that.

QUESTION
The purpose of my shiny app is for users to import an excel file, and the app will show the table (after some data manipulation). Users also can download and save the table as whatever the name they give.
The code works perfectly fine. However, when I decided to add another tabPanel, the download button works fine in the first panel, but only downloads the HTML in the second Panel rather than the table imported. If it is not clear, you can copy the code ad try and run it. The second panel only download the HTML of the page.
Why does it download the HTML in the second panel, but the same code works perfectly fine in the first panel?

Answered 2021-Jun-08 at 11:49Your second downloadButton in conditionalPanel seems to be the issue.
