Condition has length > 1
Matches: the condition has length > 1
WHAT THIS ERROR MEANS
An if() statement received a vector with multiple values instead of a single TRUE or FALSE. if() only works with single logical values.
HOW TO FIX IT
1. Use any() or all() to reduce a logical vector to a single value.
2. Use ifelse() for vectorized conditions.
3. Check which element you actually want to test.
CODE EXAMPLES
BAD — THIS CAUSES THE ERROR
x <- c(1, 2, 3)
if (x > 2) print("big")GOOD — CORRECT APPROACH
x <- c(1, 2, 3)
if (any(x > 2)) print("at least one big")Still stuck?
