## Fundamentals of String Manipulation

In previous posts, I’ve worked with variables with numerical data. This post will focus on working on variables with character data. The data set that I am using for this post was posted on Tidy Tuesday’s github. This data set comes from Spotify and provides information about popular songs and their genres. So let’s get started!

## Functionals

In a previous post, I went over vectorized functions in R. Vectorized functions are used to operate on all the elements of a vector at once. However, not all functions in R can be applied to all of the elements of a vector at once.

## Custom Functions

This post will go over DataQuest’s Writing Custom Functions lesson. I decided to continue with the movie-theme in honor of the Academy Awards that took place on Sunday. I will continue to use the data set from my previous vectorized functions post. The data set comes from Kaggle and was composed by a Kaggle member with the user name of kikun1234. It explores award nominations of movies released between 2000-2018. I loaded the data set into a data frame called oscars_2018. So without further delay, let’s get started!

## Vectorized Functions

In my last post, I went over for-loops. For-loops are a common programming task and it’s important in understanding how programming works. However, in R for-loops are not written as often as it is for other programming languages.

## Control Structures

This past weekend was the Super Bowl. I thought for this post I would use a data set that was posted on Kaggle that contains data on the Super Bowl games from 1967 to present. This data set was put together by Timo Bozsolik.

## Installing RStudio

In honor of the RStudio Conference that took place in San Francisco last week, I wanted to talk a bit about RStudio, the IDE that I’m using to practice R. This is also a lesson in the Data Analyst in R track called, Guided Project: Install RStudio.

## Working With Data Frames

Basketball has been heavy on mind lately. One reason being the All the Smoke podcast that I listen to with Matt Barnes and Stephen Jackson every week. I’ve been listening to the podcast since day one. Another reason has been the recent passing of Kobe Bryant, his daughter Gianna and the seven other lives that were taken in that helicopter accident. When I think of Kobe, I think about my brother and the kids I went to school with. They would shout ‘KOBE’ anytime they threw something.

## Working With Lists

The next topic I learned about in the DataQuest Data Analyst in R track is a list. I decided that in honor of music’s biggest night, also known the Grammys that took place last night, the examples in this post are going to be music focused. So without further ado, let’s get it started!
