Here’s the step-by-step process!

 

Example 1: Reproduce the Error in parse(text) : <text>:1:2: unexpected symbol

In this example, I’ll explain how to replicate the “Error in parse(text) : <text>:1:2: unexpected symbol” in the R programming language.

Let’s assume that we want to parse the character string “5xxx”. Then, we might try to run the following R syntax:

parse(text = "5xxx")          # Try to apply parse
# Error in parse(text = "5xxx") : <text>:1:2: unexpected symbol
# 1: 5xxx
#      ^

Unfortunately, the error message “Error in parse(text) : <text>:1:2: unexpected symbol” was returned after executing the previous R code.

The reason for this is that the character string starts with a number, and the parse function is not able to parse such character strings without further specifications.

So how can we avoid this error message? Keep on reading!

 

Example 2: Solve the Error in parse(text) : <text>:1:2: unexpected symbol

In this example, I’ll explain how to fix the “Error in parse(text) : <text>:1:2: unexpected symbol”.

For this, we simply need to wrap ” around our character string as shown below:

parse(text = "'5xxx'")        # parse works fine
# expression("5xxx")

As you can see, the error message disappeared!
