# How to Add superscripts in R (For R Plots & RMarkdown)

When you need to do a superscript in r, it is a simple and intuitive markdown to use. Any programmer would know the carat character as being used to apply an exponent to a number, this makes it a highly intuitive feature to use. It does not take long to get used to how this works.

### Description – when to use a superscript in R

To create a superscript r has a very simple feature within the plotting function. It has the format of plot(vector, main = expression(” title”^superscript)) and it works along with subscripts as well as other superscripts. It is a straightforward process to use. It is similar to the process used to denote an exponent when doing math. As a result, any programmer should be able to learn this process quite quickly. It simply uses the carat character to denote a superscript. As the result, this feature is highly intuitive for anyone who is used to programming not only in R but in other programming languages as well.

### Explanation – How To Use A Superscript in R

When you are doing a superscript in r plotting, you can use the carat character to indicate the superscript. Doing so will result in the superscript being smaller and slightly raised above the rest of the text. This feature can be used along with subscripts, and it can be placed in the middle of the title. These aspects of the superscript feature result in a high degree of flexibility for how you can format plotting titles. This degree of flexibility means that there are many potential applications for this feature. It is easy and highly intuitive to use because the format is familiar.

### Examples of using a Superscript in R

Here are four examples using the superscript feature of the plotting function. Each example shows a different aspect of this feature.

> x = 1:10
> x
[1] 1 2 3 4 5 6 7 8 9 10
> plot(x, main = expression(“Example”^1))

In this example, we use the carat character to produce a numerical superscript.

> x = c(2, 4, 6, 8, 10, 12, 14, 16, 18, 20)
> x
[1] 2 4 6 8 10 12 14 16 18 20
> plot(x, main = expression(“Example”^”B”))

In this example, we use the carat character to produce a single character superscript.

> x = c(1, 4, 9, 16, 25, 36, 49, 64, 81, 100)
> x
[1] 1 4 9 16 25 36 49 64 81 100
> plot(x, main = expression(“Example”^”CC”* “title”))

In this example, we use the carat character to produce a character string superscript. Furthermore, additional text is added to the title after it.

> y = c(1, 4, 9, 16, 25, 36, 49, 64, 81, 100)
> y
[1] 1 4 9 16 25 36 49 64 81 100
> plot(y, main = expression(“y = x”^2))

In this case, we use the carat character to produce a mathematical formula with a superscript. All these examples show how flexible the superscript feature of the plotting function is.

### Applications of using superscripts in R

There are many applications to using a superscript in the plotting function. One especially Important application is the inclusion of the registered trademark symbol. The trademark symbol is a special character used to indicate that the title is trademarked. There are other label based applications, such as numerical labeling of plots that otherwise have the same name. These are just a small example of the many applications that superscripts have.

Because this feature of the plotting function is so intuitive to seasoned programmers it is easy to learn and understand how to use it. Once you get used to using it you will probably find many more applications for it
