Worst case - I'll address them later, if not covered during the class - Respect each other - Please keep your video on. I won't face your directly but will keep the participants' window on a second screen - Lectures won't be recorded, so make all efforts to attend each class - Joseph will keep track of attendance --- ## Teaching style - Learning through practice - this means you will always do something hands-on - While doing, you will need to google for help - you will learn a lot from other resources - Always ask questions! --- ## Learning Objectives By the end of this course, you will be able to: - Understand and utilize R/RStudio - Share your code on GitHub - Understand basic data types and data structures in R - Execute and interpret some basic statistics in R - Familiarize and load data files (Excel, Comma Separated Value files) into R/Rstudio, with tips on formatting and data organization - Filter and format data in R for use with various routines - Visualize datasets using ggplot2 and understand how to build basic plots using ggplot2 syntax --- ## Rules for interaction - Post questions in a chat - If anyone knows answers, please, post them there - I'll try to allocate time at the end of each class to review the chat - Note chat history is gone as soon as the lecture is ended - [Slack](https://slack.com/). See [Slack 101](https://slack.com/resources/slack-101) - I will send invites using your VCU e-mail addresses - use them to join the [#bios524 channel](https://dozmorovlab.slack.com/archives/C01AZANCZR9) - Omit formalities, but be respectful and polite - Questions and answers posted there will be available for everyone - answer them if you can, or I'll address them - Direct messages are possible - use them to ask private questions or schedule a meeting - I'll try to answer your questions asap, typically, within 24 hours --- ## Class Assignments - Homeworks should be submitted via Blackboard, or as instructed - Homeworks are due 1 week after the class.
