 univariate 

Contains a number of functions that serve
two goals.  First, to make R more accessible to people migrating from
SPSS by adding a number of functions that behave roughly like their
SPSS equivalents. Second, to make a number of slightly more
advanced functions more user friendly to relatively novice users. The
package also conveniently houses a number of additional functions that
are intended to increase the quality of methodology and statistics in
psychology, not by offering technical solutions, but by shifting
perspectives, for example towards reasoning based on sampling
distributions as opposed to on point estimates.
