Exercise

Interacting with IRanges

You can use the IRanges() function to create a single sequence. You can also provide vectors to IRanges() to create multiple sequence ranges at the same time. This is both fascinating and useful! The creation of objects seq_1 and seq_2 are examples of this.

Remember that width = end - start + 1.

For this exercise, check the width of each of the sequences provided here, using width() and lengths(). Notice the difference between the two types of outputs.
