You may not be the best coder, but don’t lose sight of the main goal: results.

Clean code takes time.

You’ll get better.🧵

This meme was presented in John Paul Helveston’s undergrad R class...

...to blank stares, because most students were born AFTER 2003 when Pirates of the Caribbean came out.

While John got blank stares from his students, his point is well taken over here.
My code wasn’t always good.

In fact, if I look back at my early code, it was terrible.

BUT IT STILL RUNS!!!
It’s true - my tidyquant R package that’s been downloaded 800,000 times.

...Was my first R package.

...And the code is certainly not my best work.

But it gets results.

And people love it.
So don’t worry if you write unclean code at this point - especially if you’re just starting out.

You will get better over time.

If you would like to get better faster, then...

I can help.
I’d prefer it not to take you *5 years* (like it did me).

I made a free 40-minute webinar that contains the 10 most valuable tools I found when learning R.

This webinar will help speed your transformation up.
And this webinar could get you that exciting 6-figure data science job faster...

So what do you have to lose?

It's free.

Bold prediction for 2023: The Birth Of The Business Scientist.

Here's what is about to happen. 🧵

#datascience #python #rstats #stats Image
According to Glassdoor research, we already have:

1. Data Analyst, $71,298/yr
2. Business Analyst, $83,924/yr
3. Data Scientist, $124,680/yr

But noticeably missing is the "Business Scientist".
So what is a "Business Scientist"?

And why are we about to see the birth of this new role?

Having a tough time in this data science job market?

Here’s a secret.

Stop learning python.

And start learning R. 🧵

#rstats #datascience
With Twitter, Facebook & Amazon announcing massive layoffs, the job market is trickier than ever.

What do you when there’s now massive competition?
95% of data scientists are competing for the same old data science jobs.

- Python
- Pandas
- Matplotlib
- Scikit learn

If that’s your strategy, you are a commodity.

Ever have too many groups to visualize on a plot?

Here's a 3-step process I use frequently to consolidate groups with #R.

#rstats Image
Consolidating groups is super common...

I use this process for consolidating sales data all the time

(like how many purchases customers made by product over Black Friday)

And, I often have too many groups to visualize.

Here's how I get the top N groups.
There are 3 basic steps...

1. Reduce groups

2. Grouped summarize

3. Visualize

Stop learning data science.

Start learning how to solve problems. 🧵

#datascience #rstats #stats Image
Most people dive into learning data science by taking course after course on

coding,
algorithms,
math,
statistics,
computer science,
APIs,
...
web apps,
databases,
SQL,
R,
Python,
SQL again (advanced this time),
Tableau (because I like dashboards),
PowerBI (because I realized my company doesn’t use tableau),
and…

You get the idea.

This graph is exactly why I got into data science.

I was fed up with not using my brain at work.

I was bored.

And Here’s what I did.🧵

#datascience #stats Image
It was 2015.

I had recently been promoted to manager of a new sales team.

One problem. 👇

I didn’t know Sales.
I was an engineering manager that was good at selling expensive technical products.

Totally qualified right?!

Haha. Wrong.🛑

No matter how long I’ve been doing data science, I still get smacked in the face every once in a while.

True story.

#rstats #datascience
Listen, I’ve been coding in R since 2013.

I’ve published 10 R packages now.

The top 3 combine for over 2,500,000 downloads and are used at every major company that uses R.
I’ve taught over 3,000 data scientists...

... Many of them work for elite companies like Apple, Microsoft, Google, Netflix, …

AND, I still get smacked in the face every once in a while.
