This function, written by Andrew Gelman, in the arm package does an attach() that overwrites the current variable that is being attached instead of copying into R's liminal state. Very useful when working with big datasets with lots of variables.
This is a function that searches through the variable names in a dataframe and returns the matches. Does not search labels, but could easily be extended to do that, too.
Written by Paul Johnson, this extremely useful function creates "tight" regression tables (a la outreg in STATA) in R. This version prints p values at p<.01,p<.05,p<.001. I will also fix the way it prints column headings, but that will be in the next version!
