[R] other decriptive stats packages

[frenchcr]

i just found the following list, i wondered if anybody could add to this as i
have to characterize a large data set and am new to R...the list below was
so helpful....can you add to this???

Just to forestall confusion amongst those who would like to use one of 
the functions called "describe"... 

Hmisc package - describe 
numeric 
  name 
  count of observations 
  count of missing values 
  count of unique values 
  mean 
  seven quantiles 
  five lowest and highest values 
discrete (factor or numeric with <= 10 unique values) - 
  as for numeric, but 
  no mean, quantiles or low/high values and 
  including a frequency/percent display for each value. 

psych package - describe 
  item name 
  item number 
  number of valid cases 
  mean 
  standard deviation 
  median 
  mad: median absolute deviation (from the median) 
  minimum 
  maximum 
  skew (optional) 
  kurtosis (optional) 
  standard error 

prettyR package - describe 
numeric 
  name 
  mean 
  median 
  var 
  sd 
  valid.n 
the above are the defaults - the user can specify the name(s) of any 
function(s) as an argument to the function to customize the display. 
factor 
  name 
  count for each value 
  percent for each value 
  modal value 
  count of missing values 
logical 
  name 
  count of FALSE 
  count of TRUE 
  percent of TRUE 
  count of missing values



....are there any more packages that help decribe and explore data sets ????
