I just looked over the docs for the new varSelectInput and ran into trouble trying to parse this sentence: shiny/R/input-select.R Lines 240 to 244 in c790346 #' By default, \code{varSelectInput()} and \code{selectizeInput()} use the #' J

There's a little-known shiny input called varSelectInput(). Other than passwordInputs, it's the only other input I personally have never found a use for. I'm wondering if anyone knows what's it used for and can share some use cases? Based on its documentation, it seems to me that it's identical to selectInput() except you can apss it a dataframe instead of the columns of a dataframe, and when

We decided on the name “shiny.i18n” because Shiny is the most common and obvious use-case scenario for the package. At Appsilon, we are global leaders in R Shiny, and we’ve developed some of the world’s most advanced R Shiny dashboards. It is a go-to package for developing web applications. For the web app example, we’ll see how to make simple interactive dashboards that displays a scatter plot of the two user-specified columns. inputId: The input slot that will be used to access the value.. label: Display label for the control, or NULL for no label..

Value Yes, varSelectInput only exists to return symbols; it makes it a little easier to work with tidyeval, as in the example you pointed to. Otherwise, you'd have to cast the input to a symbol using sym() which is not intuitive, and the error messages wouldn't point you in that direction if you didn't. Below is the reprex as well as what I have tried already and articles I have referenced. library(shiny) library(tidyverse) dat <- tibble( state = c("lak", "cent", "east", "east"), option_1 = c("no", "yes", "no", "yes"), option_2 = c("yes", "yes", "yes", "yes"), option_3 = c("no", "no", "no", "yes"), lat = Easy interactive web applications with R.

NOTE: shiny.i18n usage is not limited to Shiny apps. You can use it as a standalone R package for generating multilingual reports or visualizations without Shiny.

1 Answer1. The problem is that ggplots aes () takes first x and y arguments and then. The first problem is that when varSelectInput allows for multiple selections it will return a list of names which needs to be spliced into aes (). Splicing !!! however only works when using the dots ( see here ).

To use the standard HTML select input element, use selectInput() with selectize=FALSE. Value By default, \ code {varSelectInput()} and \ code {selectizeInput()} use the: JavaScript library \ pkg {selectize.js} (\ url {https: // github.com / selectize / selectize.js}) to instead of the basic: select input element. To use the standard HTML select input element, use \ code {selectInput()} with \ code {selectize = FALSE}.} \ note Below is the reprex as well as what I have tried already and articles I have referenced.

Shiny - varSelectInput Select variables from a data frame varSelectInput(inputId, label, data, selected = NULL, multiple = FALSE, selectize = TRUE, width = NULL, size = NULL) varSelectizeInput(inputId,, options = NULL, width = NULL)

By default, varSelectInput () and selectizeInput () use the JavaScript library selectize.js (https://github.com/selectize/selectize.js) to instead of the basic select input element. To use the standard HTML select input element, use selectInput () with selectize=FALSE. The variable selectize input created from \ code {varSelectizeInput ()} allows deletion of the selected option even in a single select input, which will return an empty string as its value.

Essentially, I want the second varSelectInput to only provide a list we can select from that excludes the options selected with the first varSelectInput. Thus, if mpg and cyl are selected on the first one we cannot have them as options for the second. I am relatively sure one will have to do some server side ui rendering and likely some !!! or Shiny.
