Subsetting vectors

If we want to display only selected values from the object, R can help us do that easily.

For example, if we want to see the cost of the last 3 items in our food list, we would type:

cost[3:5]

Note here, that we could also type cost[c(3,4,5)] and get the same result. The : operator helps us condense the code and get consecutive values.

This exercise is part of the course

Data Science R Basics

We will learn to subset using several special operators.

Use the [ and : operators to access the temperature of the first three cities in the list, which are already stored in temp.

Have a go at this exercise by completing this sample code.

# cost of the last 3 items in our food list:
cost[3:5]

# temperatures of the first three cities in the list:
