Graphs in R - Data Visualization with R Programming Language (Udemy.com)

It is outdated, some organization could help (where to find what, code on the screen does not match successful implementation). I do not find answers on how to solve issues if I follow the screen (found in other source).

Excellent introduction to data visualization with R. The course was well structured, the code was clearly explained and the exercises were a good test of course content.

It hasn't been what I expected thus far, though I mostly interested in the ggplot2 section. However, there was no intro - we just jumped into R Studio: If I were entirely new to the topic -- this would have been extremely confusing. I should have read the course description a little better though it hasn't been hard to follow-- so far this is a recitation of the docs available in help. At halfway point, my opinion hasn't changed -- this is essentially a verbal recitation of the help docs available. In fact, there was no introduction at all -- and for ggplots sections some intro would make sense, as well as a least some indication that you need to install the plotting package.

I learned many basic options in R regarding plotting. The teacher was very knowledgeable and so I learned many new options to plot. It fitted mostly well with the knowledge I already had of R. Thank you for the course.

I enjoy the detailed lessons about graphs in base R and the default parameters. This is incredibly useful. Most instructors just want to go immediately to ggplot but an understanding of base R functionality is very valuable. The parts I found most relevant to my work were base r graphing/parameters and ggplot. Thanks Martin!

Very good course. Anecdotes on how R works are very helpful. This guy consistently produces tutorials that are directly applicable to my work. It would be really great if he produced a series on the R language itself (no packages). I still can't find any books or tutorials that really get into R from the 'theory of R' perspective.

Thanks for this course and I'm happy to share my personal experience! Valuable introduction to Base R graphics, plotrix, ggplot2 and lattice and probably everyone can get sth. out of this course. I didn't know about the gantt diagram function and like it a lot. I also found the parameters section very useful. There are some points that kept me from giving 5 stars, however: - some of the plots were hard to understand like the nested bar plot or the fan.plot which were shown without further explanation - most of the plots I did not find presentation ready. The graphs may suffice for a quick look at the data but not more. - some examples were artificial like visualizing random numbers - in several examples the code was not readable due to size of the RStudio window - Martin could have said something about the development history of the various graphical packages and give some personal comment about their advantages and also a comment why the beginner should bother to learn so many packages where one of them might suffice. A personal recommendation would be fine. - I never liked the coloration in lattice plots. A way how to change that would have been great. Good luck furher on :-)

the software version used for the examples is old. Therefore some no longer work. The narrator pronounces some words differently than what I'm used to in the US making it difficult sometime to understand what he was talking about.

This is an excellent overview of the plotting systems available in R! I would recommend finishing some basic R courses before attempting this one, since it assumes you are familiar with the general language of R.

Without any exaggeration, I should say it is well organised with examples and exercises. When I started my R Basic, had a bit difficult but later on I watched again - More clear. So, my personal suggestion as a novice, if it is expected to take over the fear of R, it is better to review the every Module at least twice with focus. Thanks Martin with the steady and consistent process of Lecture presentation.
