To get started in machine learning there are some basics that you need to know and understand before you can ever just start coding out programs. A few key areas to understand are vectors, matrices and arrays. First, what is a vector? Vectors come from linear algebra. And you thought you’d be able to forget…
So, you wanna be an Ethereum miner? It’s not really hard to do, however fair warning.. you will probably lose money. Why? The price of Ether is very volatile and using any number of mining calculators show that overtime you will probably start to lose money. I’m not going to get into hardware and costs,…

The biggest question everyone has is: how do you go about getting your first bitcoin? The most difficult task for new users is to acquire bitcoin just to get started. Being that bitcoin isn’t centralized there isn’t one right or wrong way or one right wallet. That means choice and it can make something simple…
Functions in Python can be simple or extraordinarily complex. This will teach you how to write a simple Python Function example. From there you can go on to build much more complex functions. Here is an example of a Python function that multiplies an number by itself. def double(number): dbl_num = number * number return…
R plot data doesn’t need to be boring. Being an NFL football fan has made it a lot more interesting to create lessons on learning R. There is so much NFL data that you could test endless theories on cause and effect. For this lesson we will look at both the base R plot. The…
A histogram in R is very useful to use when you want to see more detail on all of the data within your data set. A histogram in R can be used early in your data evaluation process just to get a cursory look at the data to see if it is making sense logically….
You will find occasions when you’ll need to merge data from two different data frames. In order to merge two datasets you are required to have at least one variable in common. Here is an example of how to merge data within R: > merged.data merged.data merged.data
Running a cross table, or cross tab, in R is useful for a number of applications for data research. In the example below, we run a cross tab in R to demonstrate how to find the number, or count, of weather types in a specific city. Essentially we are tallying the data. This is going…
The quantile function in R displays sample quantiles corresponding to given probabilities. The smallest observation corresponds to a probability of 0 and the largest to a probability of 1. The function’s general usage is: quantile(x, …) ## Default method: quantile(x, probs = seq(0, 1, 0.25), na.rm = FALSE, names = TRUE, type = 7, …)…
