Analysts are often trained to handle tabular or rectangular data that are mostly numeric, but much of the data proliferating today is unstructured and typically text-heavy. Many of us who work in analytic fields are not trained in even simple interpretation of natural language. Fortunately, many of the principles used to organize, analyze, and visualize tabular data can be applied to unstructured text to extract meaning from this information.
Check out the first couple text mining tutorials that have been released. Additional tutorials will be released in the coming weeks.

A.A. Milne said that “organization is what you do before you do something, so that when you do it, it is not all mixed up.” If you are not careful your data analyses can become an explosion of data files, R scripts, ggplot graphs, and final reports. Each project evolves and mutates in its own way and keeping all the files associated with a project organized together is a wise practice. Furthermore, reproducibility is crucial in any analytic project.
RStudio provides several great options for improving your analytic workflow. This includes RStudio projects, R Markdown, and the newly released R Notebook. Check out the tutorials we just released on these tools and get your analytic workflow moving in the right direction before your next project!
