# apropos & find Functions in R (2 Examples)

This tutorial explains how to **find objects by (partial) names** in the R programming language.

The tutorial will be based on the functions apropos() and find(). Let’s have a look at the basic R syntax and the definitions of the two functions:

**Basic R Syntax of apropos & find:**

apropos("partial_name") find("name") |

apropos("partial_name") find("name")

**Definitions of apropos & find:**

The apropos R function returns a character vector giving the names of objects that contain the input character (partially).

The find R function returns the location where objects of a given name can be found.

In the following tutorial, I’ll show **two examples** for the application of apropos and find in R.

So now the part you have been waiting for…

## Example 1: apropos R Function

The apropos command is used to identify R objects that contain a character string at least partially.

Let’s see how this looks in practice:

apropos("max") # Apply apropos function in R # "cummax" "max" "max.col" "pmax" "pmax.int" "promax" "varimax" "which.max" |

apropos("max") # Apply apropos function in R # "cummax" "max" "max.col" "pmax" "pmax.int" "promax" "varimax" "which.max"

With the previous R code, we identified all R objects with a name containing the character *“max”*. Insert whatever character string you want in order to identify other R objects.

By the way: The apropos function allows for many different specifications and manual adjustments. You can find all options in the R help documentation:

**Figure 1: Arguments of apropos Function.**

## Example 2: find R Function

The find command shows where an R object can be found. For instance, let’s find the location of the varimax function:

find("varimax") # Apply find function in R # "package:stats" |

find("varimax") # Apply find function in R # "package:stats"

RStudio returns *“package:stats”*.

In other words: The varimax function is part of the stats R package.

## Further Resources for the Handling of Objects in R

Objects are an important concept of the R programming language. If you want to learn more about objects in R, you could have a look at the following YouTube video of Tutorlol:
