## Example 1: Basic Application of between Function

If we want to apply the between() function, we need to install and load the dplyr package of the tidyverse first:

install.packages("dplyr") # Install dplyr package library("dplyr") # Load dplyr package |

install.packages("dplyr") # Install dplyr package library("dplyr") # Load dplyr package

Then, we also need to specify a value, an upper bound of our range, and a lower bound of our range:

x1 <- 5 # Define value left1 <- 3 # Define lower range right1 <- 8 # Define upper range |

x1 <- 5 # Define value left1 <- 3 # Define lower range right1 <- 8 # Define upper range

Now, we can apply the between function to test whether our values falls within our range:

between(x1, left1, right1) # Apply between function # TRUE |

between(x1, left1, right1) # Apply between function # TRUE

The RStudio console returns the logical value TRUE, indicating that our value is larger than the lower bound and smaller than the upper bound.

## Example 2: Value Outside of Range

Let’s illustrate what happens when we check a value outside of our range. First, we need to specify some new values:

x2 <- 10 # Define value left2 <- 2 # Define lower range right2 <- 7 # Define upper range |

x2 <- 10 # Define value left2 <- 2 # Define lower range right2 <- 7 # Define upper range

Now, we can apply the between command as we already did in Example 1:

between(x2, left2, right2) # Apply between function # FALSE |

between(x2, left2, right2) # Apply between function # FALSE

This time the between function returns FALSE to the RStudio console, indicating that our value does not fall into our range.
