问题 I'm trying to make a shiny module that will alter a datatable based on a custom searchbar. I managed to make an app that will print the results of a searchbar search into R-Studio console, but, how do I return the results from the module and update the reactive data storage? Here is an example app, I want to return what is printed to update the reactive: myModuleUI <- function(id) { ns <- NS(id) tagList( fluidRow( column(width=2, textInput(ns("searchField"), "Search"), dataTableOutput("table"

问题 I've looked on similar posts for my problem, but nothing is helping and I'm running out of patience. I have a very simple app, where I'm trying to find all counties within a selected US state. I'm using SelectInput in the UI for users to select what state they want, and an UpdateSelectInput in the server so users can select what county they want from their state selection. This is what my simplified data looks like: **STATE_NAME NAMELSAD** Alabama Clay County Alabama Marengo County Arkansas

问题 When I run a shiny application on RStudio, my app runs and the URL looks like this: Listening on http://127.0.0.1:4991 But each time I run again the app, the port changes, I wonder if there is a way to obtain the url as a variable or something like that. I mean, each time that I run the app, I want to obtain the URL and save it in a variable. Thank you 回答1: You can specify the port using options: #example: https://shiny.rstudio.com/articles/basics.html options(shiny.host = '0.0.0.0') options

问题 I'm currently working with an R Shiny App that utilizes googlesheets4 to read data in from a GoogleSheet. I recognize that authentication is important for accessing GoogleSheets, so I've tried authenticating the app using the code below in my app.R file (email and api key removed for privacy): ### AUTHENTICATE FOR GOOGLE SHEETS ACCESS ### sheets_auth( email = "MY EMAIL", path = NULL, scopes = "https://www.googleapis.com/auth/spreadsheets", cache = gargle::gargle_oauth_cache(), use_oob =

问题 I'm summarizing data and creating a table within a Shiny application. My basic problem is that I would like to add some additional spaces in between elements in a concatenated string so that it is more readable, but the spaces added seem to disappear. I think that the paste() function is appropriately adding the extra space around the "+/-" symbol, but that using either kable or kableExtra to create a table deletes the spaces. I think I'm asking the same question as this person did, but that

Once selected it will subset the data.frame and return with another data.frame to be analised.
