An example app created using R Shiny Apps

Bio builder

Bio builder is my first Shiny app. The URL to the app is https://deeptrivia.shinyapps.io/buildbio/

I tried to experiment with as many input and output methods as possible. The following slides will outline the input and output methods used

--- .class #id

Input Methods

Here is a list of all the input methods used.

1. textInput - Used to input strings - Firstname and Lastname
2. sliderInput - Slider used to input age.
3. radioButtons - Used to input Sex
4. fileInput - Used to upload photo
5. selectInput - Dropdown menu used to input educational level
6. dateInput - Used to input graduation date

--- .class #id

Output Methods and Server.R

Here is a list of all the output methods used.

1. textOutput - Used to output strings
2. imageOutput - Used to output images
3. uiOutput - Used to output a string or image dynamically based on input

Server.R does the following:

1. Concatenates various inputs to product output strings
2. Processes uploaded image for uiOutput
3. Performs time since degree calculation as shown below.

todaysdate <- Sys.Date()
inputdate <- as.Date("2000-05-01")
outstring<- paste("Time since degree:",as.character(as.numeric(todaysdate - inputdate)),"days" ,sep=" ")
outstring

## [1] "Time since degree: 5767 days"

--- .class #id

Summary

This short app demonstrates a bunch of different input and output methods, as well as some background computations (such as an elapsed time calculation.)

This is a very efficient way to deploy responsive apps.
