Every example uses real data and includes step-by-step explanations of the figures and their programming.The open source software R is an established standard and a powerful tool for various visualizing applications, integrating nearly all technologies relevant for data visualization. The basic software...
“I really like this book: those 100 interesting real data examples with the detailed R-scripts for producing beautiful graphical visualisation are particularly helpful for learning R graphics. I will use it as a main textbook for data visualization for my statistics course.” (Professor Qiwei Yao...
Write about Useful S3 Generic Methods with examples The useful S3 generic methods aresummary(),plot(),predict(). These S3 generic methods can be customized too. For example, summary.record <- function(x){ paste(x$name, "is author of", x$site) } summary(record) ...
Data visualization using R is slow for large amounts of data as compared to other counterparts. Conclusion Even with the aforementioned disadvantages, data visualization is useful as it helps in intuitive and easy understanding of the large quantities of data and thereby make better decisions based ...
