Size Estimates With Maximum (Loops)
This is a followup to Part 1 Size Estimates Vectorized.
Create a new version of your mass_from_length_theropoda() function from Part 1 of Size Estimates Vectorized called mass_from_length_max(). This function should only calculate a mass if the value of length passed to the function is less than 20. If length is greater than 20 return NA instead. Use sapply() and this new function to estimate the mass for the theropoda_lengths data from Size Estimates Vectorized.
