Welcome to Data Science: Visualization!

We’re excited to have you join us in this course, which is designed to teach you data visualization techniques to communicate data-driven findings. This is the second in a series of courses in a Professional Certificate in Data Science program. The courses in the Professional Certificate program are designed to prepare you to do data analysis in R, from simple computations to machine learning. If you need a refresher of some basic R, check out Data Science: R Basics, the first course in this series. This course assumes you are comfortable with basic math, algebra, and logical operations. HarvardX has partnered with DataCamp for some assignments in R that allow you to program directly in a browser-based interface. Verified learners will have access to additional exercises to be completed on a local installation of R.

Here’s some code

log(15) + log(22)
## [1] 5.799093
sum(2^3.14)
## [1] 8.815241
x <- log(21.22)
