Object Errors
Object not found
Matches: object '([^']+)' not found
WHAT THIS ERROR MEANS
R cannot find a variable or object with the name you used. This usually means you haven't created it yet, misspelled it, or it exists in a different environment.
HOW TO FIX IT
1. Check for typos in the variable name.
2. Make sure you ran the line that creates the variable before using it.
3. Use ls() to see what objects exist in your environment.
CODE EXAMPLES
BAD — THIS CAUSES THE ERROR
# Forgot to create the variable mean(my_data)
GOOD — CORRECT APPROACH
my_data <- c(1, 2, 3, 4, 5) mean(my_data)
