WHAT THIS ERROR MEANS

When creating a data frame, the vectors you provided have different lengths and R can't recycle them evenly.

1. Make sure all vectors have the same length.

2. Use length() to check each vector.

3. Pad shorter vectors with NA if needed.

BAD — THIS CAUSES THE ERROR

data.frame(x = 1:3, y = 1:5)

GOOD — CORRECT APPROACH

data.frame(x = 1:5, y = 1:5)
