# Lesson 4, part 2: Creating and indexing vectors 


###################################
##### CREATING NUMBER SEQUENCES
# Of course you can type in values manually to create vectors
# as we have been doing, but there are some easier way to do this:





###################################
##### VECTOR INDEXING
# Indexing refers to being able to select particular values or
# subsets of values from vectors. Indexing is done with square
# brackets '[]' and is quite intuitive once you get the hang of it.
