Please provide help using the R coding platform in using the MinnLand data (located in the alr4 package) to fit a model (I'm thinking using log(acrePrice) as the response and year as the predictor/factor to analyze housing prices in Minnesota).

US were increasing from 2002-2006, and then began to fall in 2007. How do I know if this held true for Minnesota?

Note: I'm thinking a boxplot and my regression coefficients could explain.(I know I should check my residual plots as well but not quite sure how to interpret them so that would be of great tutorial help for me as well).

I am looking assistance and will ultimately use my own inference to determine what I think is the best way to explain the answer.

No work or example code provided will ever be passed off as my own. I simply need help in understanding how to start and where to go with this problem.

I AM attempting to work this on my own but am lost.
