Let’s dive right in:

## Example 1: Create Empty Numeric Vector in R

In Example 1, I’ll show you how to create a numeric vector of zero length. For this task, we can use the numeric() function as follows:

vec_num <- numeric() # Numeric vector of 0 length |

vec_num <- numeric() # Numeric vector of 0 length

The previous R code stored an empty numeric vector in the data object vec_num. Let’s print the vector to the RStudio console:

vec_num # Print empty vector # numeric(0) |

vec_num # Print empty vector # numeric(0)

As you can see, the output is a numeric array with zero length.

We can double check the length of our vector by applying the length function:

length(vec_num) # Apply length function # 0 |

length(vec_num) # Apply length function # 0

The RStudio console shows the length of our numeric vector (i.e. 0).

## Example 2: Empty Vectors of Other Data Types

In Example 1 you have learned how to create an empty vector of the numeric data class. However, we can create a vector with zero length of basically any data type. The following R code creates empty factors, logicals, integers, and so on…

vec_cha <- character() # Numeric vector of 0 length vec_fac <- factor() # Factor vector of 0 length vec_log <- logical() # Logical vector of 0 length vec_int <- integer() # Integer vector of 0 length vec_dou <- double() # Double vector of 0 length vec_raw <- raw() # Raw vector of 0 length vec_com <- complex() # Complex vector of 0 length |

vec_cha <- character() # Numeric vector of 0 length vec_fac <- factor() # Factor vector of 0 length vec_log <- logical() # Logical vector of 0 length vec_int <- integer() # Integer vector of 0 length vec_dou <- double() # Double vector of 0 length vec_raw <- raw() # Raw vector of 0 length vec_com <- complex() # Complex vector of 0 length
