Data science for business (DS4B) is the way forward for business analytics, yet, it's really difficult to work out where to start out. The last item, you would like to try to do is waste time with the incorrect tool.
Making effective use of sometime involves two pieces:
(1) selecting the proper tool for the work, and (2) efficiently learning the way to use the tool to return business value. This text focuses on the primary part, explaining why R is the right choice in six points.
Reason 1: R Has the simplest Overall Qualities For Business.
There are several tools available for business analysis/intelligence (with DS4B being a subset of this area). Each tool has its pros and cons, many of which are important within the business context. The foremost flexible tools are harder to find out but tend to possess a better business capability. Conversely, the “easy-to-learn” tools are often not the simplest long-term tools for business or data science capability. Our opinion is to travel for capability over simple use. Of the highest tools in capability, R has the simplest mixture of desirable attributes including high data science for business capability, low cost, growth, and features a massive ecosystem of powerful R libraries. The sole downside is the learning curve.
Reason 2: R Is Data Science For Non-Computer Scientists.
If you're seeking high-performance data science tools, you've got two options: R or Python. When starting, you ought to pick one. It’s an error to undertake to find out both at an equivalent time. Your choice comes right down to what’s right for you. The difference between R and Python is always a debate, but the foremost overlooked reason is person-programming language fit. Don’t understand what we mean? Let’s break it down.
Fact 1: most of the people curious about learning data science for business aren't computer scientists.
Fact 2: Most activities in finance and business involve communication.
Now that we recognize what’s important, let’s study the 2 major players in data science.
Python: Python may be a general service programming language developed by software engineers that have solid programming libraries for math, statistics, and machine learning. Python has best-in-class tools for pure machine learning and deep learning but lacks much of the infrastructure for subjects like econometrics and communication tools like reporting. due to this, Python is well-suited for computer scientists and software engineers.
R: R may be a statistical programming language R developed by scientists that have open-source libraries for statistics, machine learning, and data science. R lends itself well to business due to its depth of topic-specific packages and its communication infrastructure. R has packages covering a good range of topics like econometrics, finance, and statistic. R has best-in-class tools for visualization, reporting, and interactivity, which are as important to business as they're to science. Due to this, R is well-suited for scientists, engineers, and business professionals.
Which do you have to Learn?
Don’t make the choice tougher than what it's. Believe where you're coming from:
• Are you a scientist or software engineer? If yes, learn Python.
• Are you an analytics professional or mechanical/industrial/chemical engineer looking to urge into data science? If yes, learn R.
• Think about what you're trying to do:
• Are you trying to create a self-driving car? If yes, learn Python.
• Are you trying to speak business analytics throughout your organization? If yes, learn R.
Reason 3: Learning R is straightforward With The Tidyverse
Learning R won’t to be a serious challenge. Base R was a posh and inconsistent programming language. Structure and ritual weren’t the highest priority as in other programming languages. This all changed with the “tidyverse”, a group of packages and tools that have a consistently structured programming interface. When tools like dplyr and ggplot2 came to fruition, it made the training curve much easier by providing a uniform and structured approach to working with data. As Hadley Wickham and lots of others continued to evolve R, the tidyverse came to be, which incorporates a series of commonly used packages for data manipulation, visualization, iteration, modeling, and communication.
R continues to evolve in a structured manner, with advanced packages that are built on top of the tidyverse infrastructure. A replacement focus is being placed on modeling and algorithms, which we are excited to ascertain. Further, the tidyverse is being extended to hide topical areas like text (tidytext) and finance (tidyquant). For newcomers, this could offer you confidence in selecting this language. R features a bright future.
Reason 4: R Has Brains, Muscle, And Heart Saying R is powerful is an irony.
From the business perspective, R is like Excel on steroids! But more important than simply muscle is that the combination of what R offers: brains, muscle, and heart.
R has brains
R implements cutting-edge algorithms including:
• H2O (h2o) - High-end machine learning package
• Keras/TensorFlow (Keras, TensorFlow)
• xgboost - Top Kaggle algorithm
• Modeltime - statistic forecasting And many more!
These tools are used everywhere from AI products to Kaggle Competitions, and you'll use them in your business analyses.
R has muscle
• R has powerful tools for Vectorized Operations - R uses
• Vectorized operations to form math computations lightning-fast right out of the box • Loops (purrr)
• Parallelizing operations (parallel, future)
• Speeding up code using C++ (Rcpp)
• Connecting to other languages (rJava, reticulate)
• Working With Databases - Connecting to databases (dbplyr, odbc, bigrquery)
• Big Data - Connecting to Apache Spark (sparklyr) And many more!
R has heart
We already talked about the infrastructure, the tidyverse, that permits the ecosystem of applications to be built employing a consistent approach. It’s this infrastructure that brings life into your data analysis. The tidyverse enables:
• Data manipulation (dplyr, tidyr)
• Working with data types (stringr for strings, lubridate for date/datetime, forcats for categorical/factors) Visualization (ggplot2)
• Programming (purrr, tidyeval)
• Communication (Rmarkdown, shiny)
Reason 5: R is made For Business
Two major advantages of learning R versus every other programming language are that it can produce business-ready reports and machine learning-powered web applications. Neither Python nor Tableau or the other tool can currently do that as efficiently as R can. The 2 capabilities we ask for are rmarkdown for report generation and glossy for interactive web applications.
Reason 6: R Community Support
Being a strong language alone isn't enough. To achieve success, language needs community support. We’ll hit on two ways in which R excels during this respect: CRAN and therefore the R Community.
R features a wide selection of advantages making it our obvious choice for Data Science for Business (DS4B). That’s to not say that Python isn’t an honest choice also, but, for the wide selection of business needs, there’s nothing that compares to R.
