Assignment 01: Working with Spatial Data

Basic use of R (lecture01):

  1. Create the vectors:
  1. (1,2,3,…,19,20)
  2. (20,19,…,2,1)
  3. (1,2,3,…,19,20,19,18,…,2,1)
  4. (4,6,3) and assign it to the name tmp
  1. Using rep () and seq () functions, create the vectors:
  1. [1] 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 and
  2. [1] 0 0 0 0 0 1 1 1 1 1 2 2 2 2 2 3 3 3 3 3 4 4 4 4 4

  1. Create a vector x which get values 1-10. Recalculate vector z values so that if the value of the x is less than 5, z=x-1, and if values of the x is something else, z=x/x.

  2. Repeat following calculation z=z+1 until z > 100. Define first that z=0. Print the result after every calculation.

  3. Write a R-function which calculate average for vector x <- c(1,2,3,4,5).

  4. Create a data frame with two variables: year and result. Variable year has values 1,2 and,3, and variable result has values 10,8 and 9. Write a R-function that create a line plot you’re your data frame.

  5. Create a permutation test and analyze whether the group mean is different between A and B groups. Calculate also Mann-Whitney test for groups. Group A: {5,6,7,5,5,6,8,9,10,15,2} and group B: {2,8,1,14,3,15,5,6,8,14,12,3} Explain your results!

Reading and mapping data with R (lecture02):

  1. Create a map of the regions of Finland (called maakunta4500k_2026). Add a north arrow and a scale bar to the map. Include both the map image and the code you used to create it in your portfolio answer.

  2. Create an interactive Leaflet map of your hometown and add what you consider the three best places in your hometown. Include the code you used to create the map in your portfolio answer.

  3. Create a map showing the municipality level urban–rural classification. Use the CSV file aluejaot_muokattu2 (found in the course’s Elearn platform under the folder Data 31.3.2026) as your dataset, where the urban–rural classification is given in English in the variable Alueluokka_eng. Use the 2023 municipal boundaries. Include the code you used to create the map in your portfolio answer.

After you have created a solution for exercise, save them with code to your portfolio.
