R Error in rep(X) : invalid ‘times’ argument (2 Examples)

 

In this post you’ll learn how to handle the “Error in rep(X) : invalid ‘times’ argument” in the R programming language.

The article will contain two examples for the handling of the “Error in rep(X) : invalid ‘times’ argument”. To be more specific, the content is structured as follows:

Let’s dive into it!

 

Example 1: Reproduce the Error in rep(X) : invalid ‘times’ argument

Example 1 explains how to replicate the “Error in rep(X) : invalid ‘times’ argument” in the R programming language.

Have a look at the following application of the rep function:

rep("a", - 5)                     # Application of rep doesn't work
# Error in rep("a", -5) : invalid 'times' argument

As you can see, the previous R code has returned the error message “Error in rep(X) : invalid ‘times’ argument”.

The reason for this error is that we have tried to use a negative times value (i.e. – 5).

Let’s fix this problem!

 

Example 2: Fix the Error in rep(X) : invalid ‘times’ argument

The following code demonstrates how to debug the “Error in rep(X) : invalid ‘times’ argument”.

For this, we have to assign a positive value to the times argument:

rep("a", 5)                       # Properly apply rep function
# [1] "a" "a" "a" "a" "a"

The previous R code has worked fine and has not returned any error messages.
