Part 1 Steps 3 & 4: typos

[cfgauss]

"There are 30 elements in this vector and we can inspect individual elements in the vector based on their ordered position using square brackets:" 31, not 30. Both vectors, day and month have 31 elements. Also "this vector" is somewhat ambiguous since the most recently mentioned vector is month rather than day.

> dim(March)
[1] 31  3

"This tells us that we have 30 rows and 3 columns." 31, not 30.

Thanks! Fixed it partially for the time being.
