middle.group
Return a vector containing the locations of the middle of every group in a vector, either as a numerical index or as a TRUE/FALSE boolean.
compareplot
Bar plot divided by three groupings
japply
japply: Judiciously sapply to only selected columns
shift
Shifts a vector's elements left or right by N elements.
sides
Figure out how many "sides" a formula has See also SimonO101's answer at http://stackoverflow.com/a/16376939/636656
fpart
Obtain the fractional part of a numeric
roundnear
Rounds a numeric vector to arbitrary values (not just decimal values as with round) or to a specified number of significant digits.
latex.table.by
Exports a latex table with the first N columns being multirow grouping variables.
panel.ecdf
Various panel functions
autoplot.microbenchmark

unfactor.data.frame
Convert all factors to character
prettify
Function to prettify the output of another function using a `var.labels` attribute This is particularly useful in combination with read.dta et al.
xtable.CrossTable
Add in methods to handle CrossTable objects in xtable
xtablelm
Produces the output of an lm object as it appears in the R console when you type summary(lmobject)
