There are several ways to visualize the output of a loop within a function using Rshiny. Here are some examples:
renderTable
function to create the table and the rbind
function to combine the results of each iteration of the loop.output$table <- renderTable({
results <- data.frame()
for (i in 1:length(input$data)) {
result <- my_function(input$data[i])
result_row <- data.frame(iteration = i, result = result)
results <- rbind(results, result_row)
}
results
})
renderPlot
function to create the plot and the plot
function to plot the results of each iteration of the loop.output$plot <- renderPlot({
results <- data.frame()
for (i in 1:length(input$data)) {
result <- my_function(input$data[i])
result_row <- data.frame(iteration = i, result = result)
results <- rbind(results, result_row)
}
plot(results$iteration, results$result)
})
plotly
package to create an interactive plot. Use the renderPlotly
function to create the plot and the add_trace
function to add the results of each iteration of the loop to the plot.output$plot <- renderPlotly({
results <- data.frame()
for (i in 1:length(input$data)) {
result <- my_function(input$data[i])
result_row <- data.frame(iteration = i, result = result)
results <- rbind(results, result_row)
}
plot <- plot_ly(data = results, x = ~iteration, y = ~result, type = "scatter", mode = "lines+markers")
plot <- plot %>% add_trace(name = "Results")
plot
})
