5. With the support of the LPP programme of the European Union 5 How it works? Working with databases possibility of migration data from xls, txt and other formats has an easy-to-use point-and-click interface providing access to its commands. Stata also has a simple, consistent command syntax. Both operations and their results are recorded and repeatable.

The ‘bin/windows’ directory of a CRAN site contains binaries for a base distribution and a large number of add-on packages from CRAN to run on Windows XP 3. R packages are installed into libraries, which are directories in the file system containing a subdirectory for each package installed there.
