Join attribute data to a polygon vector file. To clean things up and clearly separate what features we are adding to our plots, you will probably encounter two different approaches.

  • Make all of your mistakes early in life. The more tough lessons early on, the fewer errors you make later.
  • Always make your living doing something you enjoy.
  • Be intellectually competitive. The key to research is to assimilate as much data as possible in order to be to the first to sense a major change.
  • Make good decisions even with incomplete information. You will never have all the information you need. What matters is what you do with the information you have.
  • Always trust your intuition, which resembles a hidden supercomputer in the mind. It can help you do the right thing at the right time if you give it a chance.
  • Don't make small investments. If you're going to put money at risk, make sure the reward is high enough to justify the time and effort you put into the investment decision.

In this case, R will count the number of pixels that occur within each value range as follows: bin 1: number of pixels with values between 1600-1800 bin 2: number of pixels with values between 1800-2000 bin 3: number of pixelsplot.
