Example 1: Reproduce the Error: unexpected symbol in X

Example 1 explains how to replicate the error message “unexpected symbol in X” in R. Consider the following numeric vector:

x <- 1:3        # Example vector in R
x               # Print vector
# 1 2 3

Now, let’s assume that we want to multiply this vector by five:

5 x             # Reproducing error message
# Error: unexpected symbol in "5 x"

The error occurs. Why? What happened? That’s what I’ll explain next…

 

Example 2: Fix the Error: unexpected symbol in X

This Example explains how to get rid of the error message “unexpected symbol in X”. In the following R code we are inserting a mathematical operator (i.e. *) between our multiplier 5 and our vector:

5 * x           # Insert mathematical symbol
# 5 10 15

Now, it works!
