Course Code: TTDS6680

Skill Level: Introductory

Duration: 3 Days

Course Overview

R is an open-source free programming language for statistical computing, data analysis, and graphics. R is used by a growing number of managers and data analysts inside corporations and academia. R has also found followers among statisticians, engineers and scientists without computer programming skills who find it easy to use. Its popularity is due to the increasing use of data mining for various goals such as set ad prices, find new drugs more quickly or fine-tune financial models. R has a wide variety of packages for data mining. It's a language that many non-programmers can easily work with, naturally extending a skill set that is common to high-end Excel users. It's the perfect tool for when the analyst has a statistical, numerical, or probabilities-based problem based on real data and they've pushed Excel past its limits.

Introduction to R Programming is a hands-on course covers the manipulation of objects in R including reading data, accessing R packages, writing R functions, and making informative graphs. It includes analyzing data using common statistical models. The course teaches how to use the R software (http://www.r-project.org) both on a command line and in a graphical user interface (GUI).

Course Objectives

This course provides indoctrination in the practical use of the umbrella of technologies that are on the leading edge of data science development focused on R and related tools. Working in a hands-on learning environment, led by our expert practitioner, students will learn R and its ecosystem, and where it’s a better a tool than Excel.

This course is approximately 50% hands-on, combining expert lecture, real-world demonstrations and group discussions with machine-based practical labs and exercises. Our engaging instructors and mentors are highly experienced practitioners who bring years of current "on-the-job" experience into every classroom. Working in a hands-on learning environment, guided by our expert team, attendees will learn about and explore:

R Language and Mathematics
How to work with R Vectors
How to read and write data from files, and how to categorize data in factors
How to work with Dates and perform Date math
How to work with multiple dimensions and DataFrame essentials
Essential Data Science and how to use R with it
Visualization in R
How R can be used in Spark (Optional / Overview)

Need different skills or topics? If your team requires different topics or tools, additional skills or custom approach, this course may be further adjusted to accommodate. We offer additional R Programming, Python, data science, AI / machine learning / deep learning and other related topics that may be blended with this course for a track that best suits your needs. Our team will collaborate with you to understand your needs and will target the course to focus on your specific learning objectives and goals.

Course Prerequisites

Attendees for this course should have prior practical hands-on experience with another programming language. Prior exposure to working with statistics and probability, as well as hands-on working knowledge of Excel would also be helpful but is not required. We will collaborate with you to design the best solution to ensure your needs are met, whether we customize the material, or devise a different educational path to help your team best prepare for this training.

Our core R and Python programming, data science, analytics, AI and machine learning training courses provide students with a solid foundation for continued learning based on role, goals, or their areas of specialty.

The voices of our customers speak volumes

First time in my life I have attended remote class and I find it great. Personally I don't feel there is any area which require improvement!

Rishi M

Both the instructor and the course material were very thorough - the course material has many helpful references - the labs were well laid out, making it easy to learn from and get done on time

Steve C.

Excellent detail about the Spring framework which directly relates to my role as a senior engineer. I found the content and style to be very enjoyable, and would encourage me to ask questions where previously I might not have paid much attention, eg. pom version numbers / spring starters being imported. The focus on the different styles of unit testing was also excellent and I would plan to incorporate in day to day work.

Edward K

Instructor was beyond phenomenal. He had an in depth knowledge of the course material and always ensured that everyone understood what was being discussed. I really enjoyed the mix of theory and practical examples of each part of the course.

Cillian M

Great job overall. Great communicator and explained complex concepts in a simple, easier to understand format.

Jeremy G

A very good balance of teaching time to lab time. I've done other courses that I found to be much lighter on content and heavy on labs to waste time. This was a refreshing change of pace.

Adam G

Excellent training. Even though it was online, I did not have any issues understanding or getting the answers for the questions I had. The lab exercises are interesting to apply what was learnt. Overall very good training. Thank you!

Anitha

Best programming class I've ever been in, head and shoulders above any thing I took in college as part of a computer science degree. The instructor was thorough and very detailed, he was very good abut explaining all possible scenarios a situation would apply to. The way the albs were structured and the class was conducted was very good for interaction and hand on learning.

Danish J

The instructor was clearly knowledgeable about Java and programming in general. He was very attentive to every student's individual needs and constantly encouraged questions, concerns, student issues to be raised and addressed each one thoroughly.
