HereвЂ™s the code for the ui that made the Star Wars-inspired user interface: ui <- fluidPage ( titlePanel ( 'My Star Wars App' ), sidebarLayout ( sidebarPanel (), mainPanel ( h6 ( 'Episode IV', align = 'center' ), h6 ( 'A NEW HOPE', align = 'center' ), h5 ( 'It is a period of civil war.', align = 'center' ), h4 ( 'Rebel spaceships, striking', align = 'center' ), h3 ( 'from a hidden base, have won', align = 'center' ), h2 ( 'their first victory against the', align = 'center' ), h1 ( 'evil Galactic Empire.' ) ) ) ) Formatted text

If you are unfamiliar with HTML tag attributes, you can look them up in one of the many free online HTML resources such as w3schools. In general, any HTML tag attribute can be set as an argument in any Shiny tag function. You can create this effect with align = 'center', as in h6('Episode IV', align = 'center'). If George Lucas had a first app, it might look like this. ui <- fluidPage ( titlePanel ( 'My Shiny App' ), sidebarLayout ( sidebarPanel (), mainPanel ( h1 ( 'First level title' ), h2 ( 'Second level title' ), h3 ( 'Third level title' ), h4 ( 'Fourth level title' ), h5 ( 'Fifth level title' ), h6 ( 'Sixth level title' ) ) ) ) Remember to relaunch a Shiny app you may run runApp('App-1'), click the Run App button, or use your keyboard shortcuts.

Update your ui.R to match the script and then relaunch your app. The new script below uses all six levels of headers. You can place multiple elements in the same panel if you separate them with a comma. The text will appear in the corresponding panel of your web page.

pass h1('My title') as an argument to titlePanel, sidebarPanel, or mainPanel.

If you run the command at the command line, youвЂ™ll notice that it produces HTML code. Give it the text you want to see in the headerДЇor example, you can create a first level header that says вЂњMy titleвЂќ with h1('My title'). Select a header function (e.g., h1 or h5)

Edit the script to match the one below: library ( shiny ) # Define UI - ui ДЄn in-line division of text with a uniform styleДirectly passes a character string as HTML code WeвЂ™ll use the App-1 app you made in Lesson 1.

You will learn how to lay out the user interface and then add text, images, and other HTML elements to your Shiny app. This lesson will show you how to build a user interface for your app. To help us we will use the famous magritte pipe %>%.Now that you understand the structure of a Shiny app, itвЂ™s time to build your first app from scratch. To do this, we will wrap the filtering operation in a reactive() function which will update the table each time a selection is made. In fact, it makes sense: the table is not filtered. tib? SurrГ©aliste! tib <- as_tibble(sample_n(ex_df, 40)) LetвЂ™s save this data frame under the name tib. # 19 raymond filter an apple out of magrittr # 18 raymond mutate an apple without tidyr # 16 raymond slice an apple out of magrittr # 15 charlotte slice a pipe without magrittr # 13 charlotte spread a pipe thanks magrittr # 12 charlotte filter a pipe without tidyr # 11 hadley spread a cocktail without purrr # 9 raymond mutate a cocktail thanks dplyr # 8 hadley spread a cocktail out of purrr # 7 charlotte filter a pipe out of magrittr # 6 raymond mutate a dog without magrittr # 1 raymond spread a cocktail without purrr head(sample_n(ex_df, 40), 20) # var_one var_two var_three var_four var_five To simulate a parent-child data frame we will select 40 combinations using the sample_n function which selects rows randomly. Whatever the value chosen in the var_one column, the 4 values in the var_two column are right However, if we use this data frame as is, we are not in the desired situation because all combinations are available. # 14 charlotte spread an apple with tidyr LetвЂ™s check: head(ex_df, 20) # var_one var_two var_three var_four var_five ex_df <- id(a_df) # create a df with the 64 combinaisons We have 4 values and 5 columns, which will give us a total of 4^5, or 1,024 combinations. Thanks to the id() function, we will extend the data frame with all possible combinations. # 2 charlotte filter a pipe without magrittr LetвЂ™s create a surrГ©aliste data frame: a_df It is also an opportunity to refer to some of HadleyвЂ™s packages that are so attractive but just as surrГ©aliste. If you donвЂ™t know who is this painter, I really invite you to discover him and why not take the opportunity to visit the land of french fries (Whaaaat? French? So surrГ©aliste!). Therefore an opportunity for me to refer to one of the greatest surrealist painters: RГ©nГ© Magritte and one of his famous painting : The Son of Man (French: Le fils de lвЂ™homme). You know that little surrealist country so charming.
