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!
