R Error: Unexpected Input in X (2 Examples)

This article illustrates how to deal with the error message “unexpected input in X” in the R programming language.

The page contains these contents:

Let’s take a look at some R codes in action:

Example 1: Reproduce the Error: unexpected input in X

In this Example, I’ll explain how to replicate the error “unexpected input in X” in R. First, let’s create a numeric data object:

x <- 5        # Some numeric data

Now, let’s assume that we want to print this data object to the RStudio console. For some reason, we are putting a slash behind the name of our data object:

x\            # Replicating the error
# Error: unexpected input in "x\"

The error message “unexpected input in X” appears.

Example 2: Fix the Error: unexpected input in X

In this Example, I’ll illustrate how to solve the error “unexpected input in X”. For this, we simply have to remove all wrong symbols (i.e. a slash) from our code:

x             # Printing x
# 5

The value five that is stored in the data object x was printed to the console.
