R-Visualisation-and-Stats

Readme File

Hello Everyone! This is the Readme File for the Statistics and Visualisation with R Class.

This course is focusing on 2 aspects of using R for your research i.e. visualising your data and compute some basic Statistics on it.

There is much more you can do with R and R Studio and there are a lot of video tutorials you can watch and posts you can read:

• If you want to learn more on Data Wrangling with R: https://www.linkedin.com/learning/data-wrangling-in-r/welcome?u=50251009 https://datacarpentry.org/R-ecology-lesson/03-dplyr.html
• If you want to keep learn small bits over a long period of time this is a very interesting approach https://www.linkedin.com/learning/r-for-data-science- lunchbreak-lessons/exercise-files?u=50251009
• Machine Learning with R https://machinelearningmastery.com/machine- learning-in-r-step-by-step/ https://www.datacamp.com/community/tutorials/machine-learning-in-r
• If you want to learn more on using R and GIS together

More generally, the good thing of R being an Open Source software means you can find a lot of help online. If at any point of your research you get stuck on something just google the issue and 99% of times someone else posted about it already!

The best sites on where to find info and help are:

• https://stackoverflow.com/
• https://www.r-bloggers.com/
