The final answer is: To get the resultTbl you can just access the input[x]’s. Here is an example of how you can do it: library(DT) library(shiny) library(dplyr) cars_df <- mtcars selectInputIDa <- paste0("sela", 1:length(cars_df)) selectInputIDb <- paste0("selb", 1:length(cars_df)) initMeta <- dplyr::tibble( variables = names(cars_df), data_class = sapply(selectInputIDa, function(x){as.character(selectInput(inputId = x, label = "", choices = c("numeric", "character", "factor", "logical"), selected = sapply(cars_df, class)))}), usage = sapply(selectInputIDb, function(x){as.character(selectInput(inputId = x, label = "", choices = c("id", "meta", "demo", "sel", "text"), selected = "sel"))}) ) ui <- fluidPage( htmltools::findDependencies(selectizeInput("dummy", label = NULL, choices = NULL)), DT::dataTableOutput(outputId = 'my_table'), br(), verbatimTextOutput("table") ) server <- function(input, output, session) { displayTbl <- reactive({ dplyr::tibble( variables = names(cars_df), data_class = sapply(selectInputIDa, function(x){input[[x]]}), usage = sapply(selectInputIDb, function(x){input[[x]]}) ) }) resultTbl <- reactive({ dplyr::tibble( variables = names(cars_df), data_class = sapply(selectInputIDa, function(x){input[[x]]}), usage = sapply(selectInputIDb, function(x){input[[x]]}) ) }) output$my_table <- DT::renderDataTable({ DT::datatable( initMeta, escape = FALSE, selection = 'none', rownames = FALSE, options = list(paging = FALSE, ordering = FALSE, scrollx = TRUE, dom = "t", preDrawCallback = JS('function() { Shiny.

Introduction to ggplot2 Themes: Creating a Tufte Minimalist Design As data visualization continues to play an increasingly important role in communicating insights and trends, the need for aesthetically pleasing yet effective visualizations grows. One way to achieve this is by selecting a suitable theme that enhances the visual appeal of plots without compromising their clarity or readability. In this article, we’ll delve into the world of ggplot2 themes, specifically focusing on creating a Tufte minimalist design.

Pandas Dependent Columns Lookup Introduction When working with datasets, it’s not uncommon to encounter scenarios where we need to perform complex lookups or calculations based on multiple conditions. In this article, we’ll explore a specific use case involving pandas DataFrames, where we want to divide the amount from every sample in one condition by the amount from the corresponding sample in another condition, subject to certain conditions. Background Before diving into the solution, let’s briefly discuss the relevant concepts and data structures involved:

Understanding Multipart Post Requests with ASIFormDataRequest In this article, we will explore the intricacies of sending multipart post requests using ASIFormDataRequest, a popular networking library for iOS development. We’ll delve into the workings of this library and how it handles asynchronous request processing. Introduction to ASIFormDataRequest ASIFormDataRequest is a subclass of ASIHTTPRequest that allows you to send HTTP requests with form data. It’s particularly useful when working with web applications that require file uploads or other types of multipart post requests.

Memory Management for Objective-C Developers: A Deep Dive into Object Allocation and Release Introduction Memory management is a critical aspect of programming in Objective-C. Understanding how to allocate and release memory correctly is essential for writing efficient, reliable, and leak-free code. In this article, we will delve into the world of object allocation and release, exploring the best practices for managing memory in Objective-C applications. Background: Object Allocation and Retainment In Objective-C, objects are allocated on the heap using a process called memory allocation.

Printing Tables Side by Side in R Markdown In this article, we will discuss how to print tables side by side in R Markdown using the knitr package. We will use a custom function called PrintSideBySide that takes two data frames as input and prints them side by side. The Problem When working with multiple tables in an R Markdown document, it can be challenging to display them side by side.

Introduction to SAS Percentile Statements in R SAS is a popular programming language used for data analysis, reporting, and business intelligence. One of the key features of SAS is its ability to calculate percentiles, which are essential in statistical analysis. In this article, we will explore how to implement SAS percentile statements into R, a popular programming language for statistical computing. Understanding SAS Percentile Statements A SAS percentile statement is used to calculate the specified percentage of values from a dataset.

Understanding the Issue with NSTextAttachments and UITextView Height When working with UITextView in iOS, it’s not uncommon to encounter scenarios where the height of the text view increases dynamically as the user types or inserts images using NSTextAttachment. However, when multiple NSTextAttachments are present in a single UITextView, the height of the text view fails to increase accordingly. In this article, we’ll delve into the reasons behind this behavior and explore ways to overcome it.

PostgreSQL Select Two Correlated Rows and Show the Opposite of the Correlated Field In this blog post, we will explore how to achieve the goal of selecting two correlated rows from a table and showing the opposite of the correlated field in another new column. We’ll use PostgreSQL as our database management system and provide a step-by-step guide on how to accomplish this using self-joins. Background PostgreSQL is an object-relational database management system that supports various types of queries, including self-joins.
