DataCamp and R Basics

The Data Science Journey Begins

One small step for data rookie kind…..

I started playing around with R and I’ve got some things to share so let’s get into it.

Like I mentioned in my previous post I’m currently using DataCamp to learn the basics of R. It is a platform a lot like Codecademy but focused on Python, R, and data science concepts. I think the interactive editor and bright colors help keep me focused. They also have premium courses that includes a wealth of topics and added content like engaging videos to liven things up for $25 a month. If you’re curious give it a go and let me know what you think.

On to R itself. In comparison to the times I played around with other languages, it feels like a “thinking” language; It is logical, deliberate, and organized. I guess it makes sense for a language focused on statistical analysis. Here’s what some of the basics look like:

my_variable <- "Giants" #String
my_boolean <- TRUE #logical, in R can be shortened to T
my_oranges <- 6 #numeric assignment
my_apples <- 5
my_fruit <- my_apples + my_oranges
my_fruit  #Typing a variable into you editor prints the value inside. In this case  11

We’re not breaking any new ground here but we all begin somewhere. We can store numbers and strings in variables to use later. Even perform basic arithmetic. But what if you want to store more than one thing in a variable? Enter:

Vectors

If you’re familiar with arrays this is very similar. You can store variables, numerics, and logicals in it. However, you can’t mix and match them(boo) so for example:

c()   #the combine function, makes the vector
c(1, 2, 3)
c("Wonder Woman", "Batman", "Superman")
c(TRUE, FALSE, T, T)
c(F, "Jessica", 4.2) #This causes an error

Perhaps R has an answer for storing mixed data types. Time will tell. Next week I’ll go a little deeper into vectors and show you how you can use them for basic analysis (Finally!) The first step has been made!
