Here is an example of a box function which is at 66% of the screen width, has a blue background, and is used to hold a As a quick reminder, the box function is able to act as a container for data. If you’re looking to use a few of them to create a container, then you’re in luck.Ī box() function offers a lot of customization ability. The fantastic part about using the box function is that you don’t need to use all of the parameters at once. This gives you more control over the overall appearance of the user interface. There is also the option to set the box to collapsed as the default option (collapsed=TRUE). If you set collapsible to true (collapsible=TRUE), then the user will have the option to collapse the box. You also have the option with r shiny to make the box element collapsible or even collapse it by default. The height is fairly simpler, as you can adjust this to the typical units of pixels, millimeters, centimeters, or any other CSS unit. Otherwise, if you have the box in it’s own column – keep this at null as the width of the column is equal to the width of the boxplot. If you would like the width to be 1/3 the width of the column, then you would set the value of this to 4. Width of the box is based on Bootstrap, where you have a 12 column grid. Width and height are different from each other. The background color parameter is different from the status function because the status function is designed to be dynamically updated from the code, and background is designed to remain consistent. You would use the background parameter to change this to one of the 15 different colors which are available. The default background color of the box is white. This is in case you would like the background color for the box header to be different from the rest of the box. SolidHeader, is either set to true or false based on whether or not the header should have a solid background color. This can either be set to null, or primary, success, info, warning, or danger – corresponding to either nothing, blue, green, blue, orange, or red. This is in case you would like to programmatically change the color of the box on the basis of a status. The next argument, status =, sets a background color. The second two parameters (title = and footer =) are both optional, which are title and footer text which should be included in the box. The first parameter is the contents of the box, which is either the variable or function that renders the output. The 9 different parameters are able to be used in order to customize the look of the box according to your desired specifications. The box function is rendered to the User Interface directly on the Shiny server, and is directly included in the R file. You would store the output in a variable, and pass this variable directly to the box function when it’s time for the variable to be used. Remember that the content of the box is derived from other functions in your R code. The Box function has 9 different parameters, including the actual content of the box. Creating a R Shiny Box In Your Server Function If you’re building a r shiny app, consider using a series of boxes in order to create a much more intuitive and easy to understand interface. ![]() ![]() These boxes can be considered to be the “building blocks” of a Shiny dashboard similarly to how they function in Tableau. The great thing about a Box is that it can be used to create an entire dashboard based from other Shiny code. To create a box as part of your interface, Shiny has a Box function which is able to make this very easy to do. This container is what is able to hold the output from your Shiny code, whether it’s a graph or regular data output. A R Shiny Box can be thought of as a visual container on the user interface.
