summarizeDF

This function summarizes each variable that is in a data.frame.
It can be used, e.g., in an R script to write summary information 
about a data.frame into a text file that is in a version control system
so that one can see in the version control system 
whether one or more variables in the data frame have changed.

methods

Miscellaneous small tools and utilities.
Many of them facilitate the work with matrices,
e.g. inserting rows or columns, creating symmetric matrices,
or checking for semidefiniteness.
Other tools facilitate the work with regression models,
e.g. extracting the standard errors,
obtaining the number of (estimated) parameters,
or calculating R-squared values.
