htmltab: Hassle-free HTML tables in R
HTML tables are a valuable data source but extracting and recasting
these data into a useful format can be tedious. htmltab is a package for
extracting structured information from HTML tables. It is similar to
readHTMLTable() of the XML package but provides two major advantages:
- First, the function automatically expands row and column spans in the header and body cells.
- Second, users are given more control over the identification of header and body rows which will end up in the R table.
Additionally, the function preprocesses table code, removes unneeded parts and so helps to alleviate the need for tedious post-processing.
