DAT 301 Lab 3 DAT 301 Lab 3 In this lab you need to create a shiny app. Naturally, you would need to install shiny package. You can either create ui.R and server.R files, or just one .R file with both UI and server codes in it. Requirements • The app should be about some statistics topic or technique of your choice (for example: regression with various data sets, simulation of various probability distributions, confidence and prediction bands in regression, etc.). • At least two different kinds of GUI components/widgets must be included (slider, checkbox, table, tabs, menubar/selectbar, radio button, submit button, etc.) • Must include an interactive plot (you can use base plot, ggplot, or (3D) plotly) What to Submit and Where • In Canvas, you need to submit all the files necessary for your shiny app to run, so the grader can run your app. • You also need to submit in Canvas a pdf file explaining what your shiny app does, what its features are AND include the link to your app at www.shinyapps.io (see below). The description of your app doesn’t have to be detailed, especially if it is clear from the plot. If, however, your app has some interesting feature that is not obviously visible upon opening the app, you may want to point that out and explain it. This pdf file could be created, for example, using an Rmd file, but it is not required. • In addition to submission in Canvas, you need to upload your shiny app to https://www.shinyapps.io. Open an account there. It’s free for uploading up to 5 apps and for total run time of 25 hours per month. Use any credentials of your choice (NOT ASU credentials). These credentials (username and password) will not be known to me or the grader. Also, since this website is public, your shiny app will be visible to the whole world. However, it does NOT need to have any indication which could relate the app with you, nor our class, nor ASU. Upon opening account at https://www.shinyapps.io, to upload your app, go to Dashboard tab (if you are not already there) and follow the instructions given in the three steps. As you can see there, you will need to install rsconnect package. The 3rd step (DEPLOY), tells you to run library(rsconnect) rsconnect::deployApp('path/to/your/app') If your app consists of two files (ui.R and server.R), the app part in the address is the name of the folder where these two files are. If you are in Windows and you copy-paste the path, you need to change backslashes to forwardslashes in your address. Check whether it works on this webpage, and copy the link to the pdf file which you need to submit to Canvas. The grader will open your pdf file in Canvas and click on this link for grading. Keep in mind: your username and password in shinyapps.io webpage are of your own choice, and are unknown to us. Later, if you get interviews for jobs, you can use your shinyapps.io webpage to show to prospective employers (or your boss if you seek a promotion) what you can do in R, which is the main purpose of this lab. IMPORTANT: Don’t forget to include in your pdf file the corresponding link to your app at shinyapps.io. Apart from examples of shiny apps in Canvas, you can also go to shiny gallery and see a lot of cool apps, or you can run the following examples in you RStudio console. library(shiny) runExample("01_hello") # a histogram runExample("02_text") # tables and data frames 1 https://www.shinyapps.io https://www.shinyapps.io https://shiny.rstudio.com/gallery/ runExample("03_reactivity") # a reactive expression runExample("04_mpg") # global variables runExample("05_sliders") # slider bars runExample("06_tabsets") # tabbed panels runExample("07_widgets") # help text and submit buttons runExample("08_html") # Shiny app built from HTML runExample("09_upload") # file upload wizard runExample("10_download") # file download wizard runExample("11_timer") # an automated timer IMPORTANT! Copying a file/shiny app from someone or from some webpage is cheating and violates academic integrity! Also, this is NOT a group work, two students CANNOT have the same lab, i.e. the same shiny app. Copying a file/shiny from other student or a webpage automatically results in the score of 0 pts, and other possible sanctions include, but are not limited to: course failure (indicated on the transcript as a grade of E), course failure due to academic dishonesty (indicated on the transcript as a grade of XE), loss of registration privileges, disqualification and dismissal.
