LISA SHORT COURSES IN STATISTICS
LISA (Virginia Tech's Laboratory for Interdisciplinary Statistical Analysis) is providing a series of evening short courses to help graduate students use statistics in their research. The focus of these two-hour courses is on teaching practical statistical techniques for analyzing or collecting data. See www.lisa.stat.vt.edu/?q=short_courses for instructions on how to REGISTER and to learn more.

Title: Introduction to Web Scraping in R;
R is an open source software with many tools for data manipulation and analysis. The basic R packages include several data sets, as well as functions to read data from files on the local drive. This course will go over a more advanced package that will allow users to create their own data sets by compiling information from web pages.
In this course, users will learn the functions necessary to collect information from webpages, and how to manipulated compiled information into data frames. This course will provide an example of pulling a table directly from a webpage, as well as a more complex example of compiling a dataset from multiple webpages coherently. All code used in this course will be made available.
This is an advanced R course and prior knowledge in R is necessary. It is recommended that participants attend, or watch other LISA short courses in R. For a full list of courses being taught this semester, check www.lisa.stat.vt.edu/?q=short_courses. Past short courses can be viewed at www.lisa.stat.vt.edu/?q=past_courses.
Topics covered:
1) Reading HTML pages into R
2) Selecting specific HTML nodes
3) Isolating specific attributes of a node
4) Manipulating data into data frames
