I’m the type of person that will pick up a new hobby for a couple
weeks, get bored, and forget about it. But there are a few that I’ve
stuck with over the years. One of them is playing tennis! The Australian
Open just wrapped up and fun fact: I was able to attend
the tournament with my dad back in January of 2020. That was the last
place I traveled before COVID shut down the world :(.
Speaking of travel, that is another hobby of mine. This time
last year, I was actually studying abroad in London. It
was an amazing experience that I wouldn’t change for the world.
One of my favorite movies is The Sound of
Music. It’s one of the first movies I remember ever seeing because
my grandma would put it on when I was younger and we would sing Do-Re-Mi
together. I recently rewatched it and, upon finishing, I immediately
restarted it. Something I failed to appreciate as a child was how
beautiful the setting was. The movie was filmed in Salzburg, Austria and
the scene of Julie Andrews singing in the
mountains hills was filmed using a helicopter that
was circling her. The movie as a whole is just a classic. The songs are
super catchy, the scenes are aesthetically pleasing and it’s set against
the historical backdrop of WWII. It’s a movie I will always go back to
for familiar comfort.

The upcoming code defines two vectors, v1 and v2. The first operation multiplies v1 by v2. The second operation adds 5 to each element in v1. The third operation subtracts v1 from v2.
v1 <- c(2,3,4,5)
v2 <- c(25)
v1 * v2
## [1] 50 75 100 125
v1 + 5
## [1] 7 8 9 10
v2 - v1
## [1] 23 22 21 20
When eval = FALSE, the result of each operation is not printed out, just the operation.
