Missing value in condition
Matches: missing value where TRUE\/FALSE needed
WHAT THIS ERROR MEANS
An if statement or while loop received NA instead of TRUE or FALSE. This happens when the condition evaluates to a missing value.
HOW TO FIX IT
1. Check if your condition variable contains NA.
2. Use is.na() to handle missing values.
3. Add na.rm = TRUE to functions like any() or all().
