This is a follow up to Use and Modify.
To make it even easier to work with your dinosaur size estimation functions you decide to create a function that lets you specify which dinosaur group you need to estimate the size of by name and then have the function automatically choose the right parameters.
Create a new function get_mass_from_length_by_name() that takes two arguments,
the length and the name of the dinosaur group. Inside this function use
if/else if/else statements to check to see if the name is one of the
following values and if so set a and b to the appropriate values.
a = 10.95 and b = 2.64 (Seebacher 2001).a = 0.73 and b = 3.63 (Seebacher 2001).a = 214.44 and b = 1.46 (Seebacher 2001).If the name is not any of these values set a and b to NA.
Once the function has assigned a and b have it run get_mass_from_length()
with the appropriate values and return the estimated mass.
Run the function for:
Challenge (optional): If the name is not one of values that have a and
b values print out a message that it doesn’t know how to convert that group that includes that groups name in a message like “No known estimation for Ankylosauria”. (the function paste will be helpful here). Doing this successfully will modify your answer to (4).
Challenge (optional): Change your function so that it uses two different
values of a and b for Stegosauria. When Stegosauria is greater than 8
meters long use the equation above. When it is less than 8 meters long use a =
8.5 and b = 2.8. Run the function for a Stegosauria that is 6 meters
long.
