Exercise 2

After working through Exercise 2, you’ll…

• have double-checked whether you understand how to import data
• have learned to subset variables in data frames
• have learned to subset observations and values in data frames

Task 1

Download the “WoJ_names.csv” from LRZ Sync & Share (click here) and put it into the folder that you want to use as working directory.

Set your working directory and load the data into R by saving it into a source object called data.

Note: This time, it’s a csv that is separated by semicolons, not by commas.

Task 2

Now, print only the column to the console that shows the trust in the government. Use the $ operator first. Then try to achieve the same result using the subsetting operators, i.e. [].

Task 3

Print only the first 6 trust in the government numbers to the console. Use the $ operator first. Then try to achieve the same result using the subsetting operators, i.e. [].
