# R Output

Write R code.

From the Displayr release of the 7th June 2021, an *R Output* is referred to as a **Calculation** or **Custom Calculation**.

A *Calculation* is an *object* that's been created using R code. Typically, it consists of data, the result of a calculation of some kind (e.g., the fitting of a statistical model), or an image. It can be more than one of these at the same time. These objects are referred to in the menus as **Calculation**.

# The roles of Calculations in Displayr

A *Calculation* performs two related roles within Displayr:

- They are, as the name suggests, the results of a calculation that appear on a Page in Displayr.
- They are data or results that can be referred to by other
*Calculations*and*Variables*constructed using R.

# Creating a Calculation

*Calculations* are created by:

- Selecting
**Calculation > Custom Code**and entering code in the**R CODE**box in the Object Inspector and pressing**Calculate**. - Choosing options from the menus, many of which are the results of
*Calcuations*.

# Appearance of a Calculation

A *Calculation* can appear as a:

*Table*. While this looks like a*Table*, it is both created in a different way to a table, and has different functionality when the user interacts with it. See Tables.*Plot*. That is, a chart.*Text*. This will look like a*Textbox*, but is modified via*R CODE*.
