problema con mutate no actualiza la columna con la variable

shiny
2

mutate() is interpreting columna as a symbol, not as a character string, the syntax you are trying to use is too ambiguous, you would have to do something like this instead.

library(shiny)
library(tidyverse)

ui <- fluidPage(
    titlePanel("My question"),
    sidebarLayout(
        sidebarPanel(
            selectInput(inputId = "selectedvariable",
                        label = "Select a variable",
                        choices = names(iris))
        ),
        mainPanel(
            DT::dataTableOutput("table")
        )
    )
)

server <- function(input, output) {
    output$table <- DT::renderDataTable({
        iris %>% 
            mutate(!!sym(input$selectedvariable) := !!sym(input$selectedvariable) / 100) %>% 
            head(5)
    })
}

shinyApp(ui = ui, server = server)
