ISCAM: Investigating Statistical Concepts, Applications, and Methods

Data files for this textbook are available at:

For Interactive Sage Cells: Since Sage cells cannot access external URLs, we create small datasets directly in the code using data.frame(). This is ideal for learning concepts with manageable examples.

For RStudio: You can load data files directly from URLs using read.table(url(...)) or download files to your computer and use file.choose() to browse for them.

For Larger Datasets: When working with substantial datasets or conducting more complex analyses, we recommend transitioning to RStudio where you have full access to R’s capabilities and can manage larger data files effectively.
