6 Reasons To Learn R For Business

个税抵扣 房贷利息“认贷不认房”



Data science for business (DS4B) is the future of business analytics yet it is really difficult to figure out where to start. The last thing you want to do is waste time with the wrong tool. Making effective use of your time involves two pieces: (1) selecting the right tool for the job, and (2) efficiently learning how to use the tool to return business value. This article focuses on the first part, __explaining why R is the right choice in six points __. If you’d like to tackle learning R efficiently, we have another article that covers the 80/20 Rule for Learning R.

Reason 1: R Has The Best Overall Qualities For Business

DS4B Tool Ratings

我们不妨借用一些狄更斯的名句,来回顾下几乎各种战略都失灵的2014年:
Shanghai is the most popular destination for new job seekers, followed by Shenzhen, Guangzhou and Beijing. Provincial capitals cities in central and western regions are also among the top choices for the new graduates.

The housing slump has cut demand for iron ore, energy and other commodities. Higher global supplies have exacerbated the gap between supply and demand and pushed raw materials prices lower. This dynamic is not expected to change in the near term despite measures such as the interest rate cut in November.

  • 贵州首家全宅智能家居体验中心 智能化装修设计
  • Cost (Free/Minimal, Low, High)
  • 用AI实现家居智能 先要理解家庭状态和人的意图

Further discussion on the assessment is included in the Appendix at the end of the article.

What we saw was particularly interesting. A trendline developed exposing a tradeoff between learning curve and DS4B capability rating. The most flexible tools are more difficult to learn but tend to have higher business capability. Conversely, the “easy-to-learn” tools are often not the best long-term tools for business or data science capability. Our opinion is go for capability over ease of use.

Of the top tools in capability, R has the best mix of desirable attributes including high data science for business capability, low cost, is growing very fast., and has a massive ecosystem of powerful R libraries. The only downside is the learning curve. The Cheat Sheet below showcases the powerful libraries that are at your fingertips - 统计局:一季度楼市销售额涨54% 库存7.35亿平米 to see what libraries are available to solve specific needs.

Reason 2: R Is Data Science For Non-Computer Scientists

If you are seeking high-performance data science tools, you really have two options: R or Python. When starting out, you should pick one. It’s a mistake to try to learn both. Your choice comes down to what’s right for you. 中央经济工作会议再强调 “房住不炒”楼市调控总基调不变 has been described in numerous infographics and debates online, but the most overlooked reason is person-programming language fit. Don’t understand what we mean? Let’s break it down.

Fact 1: Most people interested in learning data science for business are not computer scientists. They are business professionals, non-software engineers (e.g. mechanical, chemical), and other technical-to-business converts. This is important because of where each language excels.

Fact 2: Most activities in business and finance involve communication. This comes in the form of reports, dashboards, and interactive web applications that allow decision makers to recognize when things are not going well and to make well-informed decisions that improve the business.

About Python

Python is a general service programming language developed by software engineers that has 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 such as reporting. Because of this, Python is well-suited for computer scientists and software engineers.

About R

R is a statistical programming language developed by scientists that has open source libraries for statistics, machine learning, and data science. R lends itself well to business because of its depth of topic-specific packages and its communciation infrastructure. R has packages covering a wide range of topics such as econometrics, finance, and time series. R has best-in-class tools for visualization, reporting, and interactivity, which are as important to business as they are to science. Because of this, R is well-suited for scientists, engineers and business professionals.

  • Are you trying to build a self-driving car? If yes, learn Python.

  • Are you trying to communicate business analytics throughout your organization? If yes, learn R.

Reason 3: Learning R Is Easy With The Tidyverse

Learning R used to be a major challenge. Base R was a complex and inconsistent programming language. Structure and formality was not the top priority as in other programming languages. This all changed with the “tidyverse”, a set of packages and tools that have a consistently structured programming interface.

When tools such as dplyr and ggplot2 came to fruition, it made the learning curve much easier by providing a consistent and structured approach to working with data. As Hadley Wickham and many others continued to evolve R, the tidyverse came to be, which includes a series of commonly used packages for data manipulation, visualization, iteration, modeling, and communication. The end result is that R is now much easier to learn (we’ll show you in our next article!).

Source: tidyverse.org

R continues to evolve in a structured manner, with advanced packages that are built on top of the tidyverse infrastructure. A new focus is being placed on modeling and algorithms, which we are excited to see. Further, the tidyverse is being extended to cover topical areas such as text (tidytext) and finance (tidyquant). For newcomers, this should give you confidence in selecting this language. R has a bright future.

Reason 4: R Has Brains, Muscle, And Heart

Saying R is powerful is actually an understatement. From the business context, R is like Excel on steroids! But more important than just muscle is the combination of what R offers: brains, muscle, and heart. The 2nd page of the R Cheat Sheet (FREE DOWNLOAD) links to all of the tools discussed next (and more tools beyond)!

  • Keras/TensorFlow (keras, tensorflow) - Go-to deep learning packages
  • xgboost - Top Kaggle algorithm
  • And many more!

R has muscle

R has powerful tools for:

  • Bottoms Up is the revolutionary new way to serve beer. The Bottoms Up system saves time, eliminates waste and awes customers!
  • 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)
  • Handling Big Data - Connecting to Apache Spark (sparklyr)
  • And many more!

R has heart

We already talked about the infrastructure, the tidyverse, that enables the ecosystem of applications to be built using 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 Built For Business

Two major advantages of learning R versus every other programming language is that it can produce business-ready reports and machine learning-powered web applications. Neither Python or Tableau or any other tool can currently do this as efficiently as R can. The two capabilities we refer to are rmarkdown for report generation and shiny for interactive web applications.

Rmarkdown

Rmarkdown is a framework for creating reproducible reports that has since been extended to building blogs, presentations, websites, books, journals, and more. It’s the technology that’s behind this blog, and it allows us to include the code with the text so that anyone can follow the analysis and see the output right with the explanation. What’s really cool is that the technology has evolved so much. Here are a few examples of its capability:

Shiny

Shiny is a framework for creating interactive web applications that are powered by R. Shiny is a major consulting area for us as four of five assignments involve building a web application using shiny. It’s not only powerful, it enables non-data scientists to gain the benefit of data science via interactive decision making tools. Here’s an example of a Google Trend app built with shiny.

Conferences

Until now, the appeal of Bigcommerce’s eponymous technology has been simplicity and its ability to scale along with merchants as they grow. “To some, this will mean the difference between success and failure,” said Steve Case, who as a board member advises Bigcommerce on U.S. entrepreneurial trends. “Even just five years ago, if you wanted to create a compelling offering, it could cost hundreds of thousands of dollars. Now, you can get up and running in hours for less than $100 per month.”

Conclusion

R has a wide range of benefits making it our obvious choice for Data Science for Busienss (DS4B). That’s not to say that Python isn’t a good choice as well, but, for the wide-range of needs for business, there’s nothing that compares to R. In this article we saw why learning R is a great choice. In the next article we’ll show you how to learn R using the 80/20 Rule.

  • Business Capability (1 = Low, 10 = High): How well-suited is the tool for use in the business? Does it include features needed for the business including advanced analytics, interactivity, communication, interactivity, and web apps?

  • Ease of Learning (1 = Difficult, 10 = Easy): How easy is it to pick up? Can you learn it in a week of short courses or will it take a longer time horizon to become proficient?

  • Cost (Free/Minimal, Low, High): Cost has two undesirable effects. From a first-order perspective, the organization has to spend money. This is not in-and-of-itself undesirable because the software companies can theoretically spend on R&D and other efforts to advance the product. The second-order effect of lowering adoption is much more concerning. High-cost tools tend to have much less discussion in the online world, whereas open source or low-cost tools have great trends.

  • Trend (0 = Fast Decline, 5 = Stable, 10 = Fast Growth): We used StackOverflow Insights of questions as a proxy for the trend of usage over time. A major assumption is that growing number of Stack Overflow questions is that the usage is also increasing in a similar trend.
