QUESTION
I want to safely allow my app users to be able to manipulate the dataset in my shiny app - by passing code to a data %>% mutate (input$textInput1), and then updating a reactive value containing the manipulated data, v$data.
There are answers for how to use a single, pre-named input and parse it, but I can't extrapolate to how to define this for several text inputs. e.g. 'input$textinput1','input$textinput2'..
Pressing the recode button with an activated input field causes the error:
...
Warning: Error in : Problem with `mutate()` input `..1`. x :1:1: unexpected '[[' 1: [[ ^ ℹ Input `..1` is `eval.secure(parse(text = paste0("[[input$recode_call", >i, "]]")))`. 94:
ANSWER
Answered 2021-Feb-03 at 11:18The following code captures a dynamic number of textInputs and converts them to code matching: 'Variable name' 'Code call'. These must be handled separately by rlang evaluation since anything left of := must be a symbol. The chain of functions transform a textInput to actionable code.
I have tried to understand why this works (edits welcome by those who understand rlang/tidyeval!):
For each of the additional textInput boxes created, a counter allows an anonymous function to loop over and create and paste together valid input name, e.g. input$recode_call1. This is then evaluated as text, parsed into an expression, where it is evaluated and interpreted, and then turned into an expression.
Unanswered questions about this answer:
- Error possibilities. Can certain inputs create bugs?
- Security concerns. Can / should
rlang::eval_tidy()be swapped out for, e.g.unix::eval.safe()? - Is there an easier / more secure way to handle the dynamic input?
QUESTION
I am programming a simple UI using WINAPI. I have a problem with compilation insisting on using the A version of the functions despite my UNICODE definition. I have two version of a code one working but not ideal for what I wished, and other packed into the constructor of a class. The code provided has compiler error and does not build.
Sorry if the question is long and full of code,didn't know how to explain it without examples but I hope too much is better than too little.
Compiling on default Visual Studio 2017 compiler.
MainWindow class is inheriting from BaseWindow template class. The working version with default constructor being as follow:
...ANSWER
Answered 2020-Nov-16 at 18:21It appears the main problem is you defined UNICODE in only one of your source files instead of all of them. One way to avoid this problem in Visual Studio is to define UNICODE as a preprocessor definition in your project settings.
The setting is
Project Properties -> C/C++ -> Preprocessor -> Preprocessor Definitions
Make sure to add this setting for all configurations instead of only the current.
QUESTION
I have a render function as below. I am taking an open-source library from our current site and building it into react, and it creates a colour picker (when we get it working), http://www.booneputney.com/jquery-hex-colorpicker.html Demo 1. We wish to continue using this as it's a nice simple colour picker.
The only issue I am trying to move the dynamic building of the picker into the render() function. I'm reasonably new to React, and I've searched high and low for an answer... but it renders the tags and so on like so in the browser.

I would like to update the colours of my pickerInput based on input from the colourInput in the below example.
This questions follows on from this question and replicating this with pickerInput instead of selectizeInput.
This works great with selectizeInput:

QUESTION
I am having a problem with shiny Select input and I would appreciate it if sb could help. I was trying to create a plot where the user could change the colour of the chart upon his request. It seems that somehow if the names of the inputs in Selectinput are with hyphens then the renderplot will return nothing. When I remove the hyphen from the name(e.x. A2019 instead of A-2019) the renderplot returns the correct plot and everything works fine. I have been trying for hours to fix it without any success. What am I doing wrong in my syntax?
...ANSWER
Answered 2020-Jul-31 at 08:17The issue is not related to SelectInput not accepting names with hyphens. In general, if you want to name a variable or list elements or dataframe columns uisng hypthens or spaces or ... you have to put the name in backticks "`".
Hence, adding backticks to the paste statement inside renderPlot solves the problem. Try this:
QUESTION
I am having problems with generating an output in shiny where I want the client to manually change the colour upon their request and the data is reactive. I simply get a blank page and nothing shown into it apart from the selectInput filter, and the dropdown item, but not the plot.
My attempt consisted of a combination of lapply with colourpicker function and created a dropdown item where the user can pick the colour he likes. Unfortunately, I could not provide a reproducible example or the dataset because there is data that could not be shared and I apologise in advance. I hope that someone might recognize the problem by looking at the code in case it is very obvious. In summary the data that has been used for this example consists of three columns: title, partner, quantity(e.x. a title of a book, the partner that prints it and the number of copies printed).
I believe that it has to do sth with the 3 lines of code for the 'cols' before I generate the plot inside the renderPlot. I would greatly appreciate if sb could lead me in the right direction. Thanks a lot in advance.

Answered 2020-Jul-29 at 21:31Your app works fine. I added the following lines at the very top of your code to simulate your input data, and it works great.
QUESTION
I would like to create a ternary plot dashboard using Shiny. But I am stuck in this error. This code takes a CSV file and updates the three drop-down input. Then the ternary plot created has upon these three drop-down values.
The problem is when adding "geom_point()" to obj I get this error -> CoordTern requires the following missing aesthetics (tlr->xy) : z
The same but different problem when want to add stat_density_tern I get this error -> stat_density_tern requires the following missing aesthetics: z
...ANSWER
Answered 2020-Jul-10 at 18:16To make your app work you can simplify your code by getting rid of your reavtive expressions Tx and pass the selected columns directly to ggtern via aes_string. Also to make ggtern work with the geom_point or geom_density we have to name the aesthetics. Try this:

...ANSWER
Answered 2020-Mar-25 at 01:46You seem to be running configure from "msys" subsystem of MSYS2 which is a POSIX-like system not meant to be used for compilation.
You should launch mingw64.exe or mingw32.exe instead to build native MSW software using MinGW and then configure should work just fine there.
