Shrub Volume Data Frame

This is a follow up to Shrub Volume Vectors.

One of your collaborators has posted a comma-delimited text file online for you to analyze. The file contains dimensions of a series of shrubs (ShrubID, Length, Width, Height) and they need you to determine their volumes (l * w * h). You could do this using a spreadsheet, but the project that you are working on is going to be generating lots of these files so you decide to write a program to automate the process.

Download the data, use read.csv() to import it into R, and then use the $ operator to print out:

  1. The shrub lengths
  2. The volume of each of the shrubs
